Compaction experiments and expansibility index indoor experiments of undisturbed expansive soil and expansive soil mixed with sand ranging from 10 % to 50 % have been made. Through the test mixing undisturbed expansive soil with different content of weathered sand,it can change the expansive soil water characteristics and compaction characteristics. It can influence the expansibility of the expansive soil index and significantly inhibit the expansibility of the expansive soil and reach the standard of roadbed filler.展开更多

In addition, it is one of the rare places because of its plant diversity and is also one of the important plant areas of Turkey. The ski run constructions are rapidly increased in the past decades in the alpine and subalpine belts of the mountain. Rate of nitrogen mineralization and some properties of soft were investigated in the soils of the three ski runs and undisturbed neighborhood forest sites. These ski runs are at the upper part of the forest belt in the mountain. Abies bornmuelleriana forest community is the postclimax and very sensitive to destruetion. The rates of the nitrogen mineralization in the soils were determined in controlled conditions （60% water-holding capacity, 20℃）. Nitrification and nitrogen mineralization were in the ski run inside where the natural recovery started, increased compared with the outside of the ski runs. Waterholding capacity, organic carbon, and total nitrogen were decreased in the massive damaged ski run, and due to these changes, the rates of mineralization and nitrification were also decreased.展开更多

This paper relies on the Shun Ping Yu subordinate Fertgbo bridge rebuilding project, detailing the cast-in-place box beam formwork support system safety special construction plan, focuses on box girder formwork design scheme of foundation design, box girder bracket design and box girder formwork design, to provide a reasonable reference for similar projects.展开更多

Whether the transformation development work of secondary college can succeed or not directly decide whether the transformation work of the whole college can carry on smoothly or not. This essay, by establishing eighteen secondary indicators, investigates seven aspects of the newly-built local undergraduate colleges and universities secondary college transformation work, such as the general idea, specialty construction, talents training mode, teaching staff construction, integration of production with teaching, social services and quality assurance, hoping that it can play a reference to the work of other colleges and universities.展开更多

Combined with successful cases, this study analyzed and showed that one should not only deal with the relationship between the original architectural style and construction of modem cities in the process of renovation design of the old industrial building space. More attention should also be paid to create new space to meet the functional requirements of the modem features, and then complete substantial renovation of old industrial building space through the innovative design. In the use of aesthetic innovative design for the renovation of the old industrial building space, people must respect the space of old industrial buildings as the prerequisite of the renovation design. It is needed to expound the local space reconstruction methods and design principles respectively on the basis of respect. And then one should grasp the whole space and make the structured design and reasonable use according to the new space functional requirements of different functional areas. This paper attempted to learn from environmental art study on the renovation of old industrial buildings space and in terms of innovative design. The authors explored the innovative thinking on the renovation design of old industrial building space through the analysis of the reality.展开更多
