Friction Characteristics Between Marine Clay and Construction Materials

Structure-soil interface friction characteristics is of importance to investigate the interaction between engineering structures and soils,especially for offshore structures.The interface friction behavior between marine clay and structural materials with different roughness was studied in this paper by using 3D optical scanning tests,a modified direct shear device and numerical simulation.Relationships between the surface roughness of structures,water content and interface friction angle were presented by model tests.The increase of water contents decreased the interface friction angles.For interfaces with different roughness,the interface friction angles will be smaller than that of the soil when the water content exceeds a certain value.The roughness of the interface and the water content of the soil are mutually coupled to influence the coefficient of friction(COF).This paper proposed a Finite Element Method(FEM)to simulate the interface direct shear tests of structures with different roughness.The surface models with different roughness are established based on the structure data obtained by 3D scanning.The Coupled Eulerian-Lagrangian(CEL)approach was employed to analyse soils sheared by irregular surfaces.The interface behavior for interfaces with different roughness under cyclic shear stresses was analyzed by FEM.

Progress on Research and Construction of Marine Ranching along the Coast of Shandong Province of China

As a new fishery mode of low-carbon economy, marine ranching has played an important role in promoting sustainable development of fishery and construction of ocean economic zone in China. Since the year of 2000, environment improvement, stock enhancement and mariculture development have been given very high degree of importance along the coast of Shandong Province of China. Studies and tests on artificial reefs and marine ranching, including effect investigation of artificial reefs set up in Jiaonan coastal areas in 1980s, hydrodynamic characteristics experiment of artificial reef, study on material and configuration of artificial reef models, algae transplantation and seaweed beds construction, stock enhancement and releasing etc., have been carried out in recent years. Furthermore, the Restoration Plan of Fishery Resources of Shandong Province has been implemented since the year of 2005, which greatly boosted the construction of artificial reefs and marine ranching along the coast of Shandong. By June of 2010, the total investment on the construction of artificial reefs and marine ranching is over $77 million USD. One hundred artificial reef districts, with total area about 33,350,000 m2 have been set up. The construction of marine ranching along the coast of Shandong Province has been in certain scale and the economic, social and ecological effects are obvious.

Marine Ecological Civilization Construction Based on Marine Ecological Culture

Marine ecological civilization is an important part of the socialist ecological civilization, and marine ecological civilization construction is the fundamental way to realize the sustainable development of coastal economy and society. Moreover, it has great theoretical and practical signifi- cance. In this paper, from the perspective of marine ecological culture, the important significance of building marine ecological civilization was ex- plored, and the problems existing in marine ecological civilization construction were analyzed from four aspects of management system, marine in- dustry, ecological action and marine culture. According to the problems, a series of measures to build marine ecological civilization were put for- ward, such as improving marine management system, optimizing marine industrial structure, strengthening infrastructure construction in coastal are- as, and speeding up the development of marine cultural creative industries.

Energy-based marine ecological footprint in Shandong province, China

An energy-based ecological footprint model was set up to monitor the sustainable development status of a specific marine system. This model used unit energy value and energy density to convert the consumption into ecological productive areas. It can reflect the utilization degree of resources in the regional development. Then, the quantitative analysis of sustainable development was done by comparing the size of the areas. We defined the concept of energy-based ecological footprint of marine and built energy-based ecological footprint model of marine. Then we applied this model to marine ecological system of Shandong province to evaluate its sustainable development statue. The results showed that the energy-based marine ecological footprint of the marine ecological system in Shandong province was 1.74 × 106 hm^2 in 2010, and the energy-based ecological carrying capacity of this area was 1.60×107 hm^2 per capita. Thus, the marine ecological system of Shandong province has strong sustainability.

Study on Potential Problems of Shandong Economic Forest Construction and Standardization Construction Scheme

Shandong is a culturally powerful province with excellent natural geographical condition and the warm temperate monsoon climate creates abundant benefits to the agricultural development there.In 2009,Shandong administration bureau of Yellow River economic development held the forum on related issues of national new countryside industry office planning to build economic forest base around the Yellow River in Shandong.The primary intention was settled and the construction of Shandong Economic Forest was formally started.Although impressive progress has been achieved in recent years,there also exists potential problems in the construction of economic forest,among which heavy metal pollution and soil acidification are the worst,causing huge damage to the physiological health of the consumers of economic forest.The writer proposes the countermeasures against standardization construction of economic forest.Scientific management is to be adopted to improve the professional skills of the employees in economic forest and brand innovation should be emphasized to quicken the quality certification of the products of economic forest.Besides,standard production demonstration is to be created and promoted in order to boost scale development.Furthermore,mechanism innovation is also to be stressed and forestry specialized cooperation organizations should be largely supported.

Engineering and microstructure properties of contaminated marine sediments solidified by high content of incinerated sewage sludge ash

Management of incinerated sewage sludge ash(ISSA)and dredged contaminated marine sediments(CMSs)is a great challenge for Hong Kong and other coastal cities due to limited landfilling capacity.The present study investigates the use of high content(20%of sediment by mass)of ISSA in combination with cement/lime for solidification/stabilization(S/S)treatment of CMSs to provide a way to reuse the wastes as construction materials.The results showed that ISSA being a porous material was able to absorb a large amount of water rendering a more efficient solidification process of the marine sediment which normally had a very high water content(w80%).The S/S treatment improved the engineering properties of the sediment,but reduced the workability,especially for the lime-treated samples.Lime can be used to replace ordinary Portland cement(OPC)for better heavy metal immobilization and carbon emission reduction.The hardened sediment samples prepared with 10%of lime and 20%of ISSA could attain a strength of 1.6 MPa after 28 d of curing.In addition,leaching tests confirmed that there was no environmental risk induced by these stabilized materials.The formation of hydrated cementitious compounds including calcium silicate hydrate(CeSeH)/calcium aluminate silicate hydrate(C-A-S-H)/hydrocalumite/calcite was mainly responsible for the strength development in the ISSA/lime-treated sediments.

中国共产党乡村文化建设的举措与经验——以晋冀鲁豫边区(1946-1948)为中心的考察

为了稳定后方,支援抗战,中国共产党在晋冀鲁豫边区不断进行革命和建设,特别注重提高乡村文化水平。这些乡村文化建设的举措充分反映在晋冀鲁豫《人民日报》的文本中。当时乡村建设以毛泽东新民主主义文化思想为指导,在改造旧艺人的同时,加强各种新旧文艺活动的展演;通过全民写稿的方式调动百姓投身办报事业,并利用文化棚、骡马大会等空间进行基层文化建设和信息传播;将卫生防疫与体育锻炼相结合,提高人们身体素质。总之,这些文化建设是党组织人民、发动人民、依靠人民的写照,并从中积累了宝贵的经验,如组织群众、参与式发展、文艺源于生活又服务于生活等。这些经验可以为当代乡村振兴提供重要借鉴。

明代山东海防工程述论

从明朝初年开始,倭寇频频大规模侵扰我国,使沿海地区深受其害。为了抵御倭寇侵扰,明政府在山东沿海陆续设立11个卫、6个守御千户所,并建设了府城、县城、卫城、所城、军寨、墩堡等海防工程,形成了以卫所城池为主体的、防止倭寇入侵和海盗骚扰的完整而严密的海防工程体系。这些海防工程在当时适应了抗倭斗争的需要,是明代山东海防体系的重要基础、重要依托,对抵御倭寇侵扰起到了十分重要的作用。
