清哈尔滨市城市堤防堤基处理工程建设方案

哈尔滨是国家确定的与大江大河的防洪有密切关系的25个重点城市之一。1958年国家投资3000万元建设了具有40年一遇防洪能力的城市防洪堤,西起正阳河、东至阿什河,全长42.8km。从上游向下游包括顾乡大堤、道里江堤、道外江堤、港务局附近河口横堤、东大坝、阿什河堤,另外有防御松花江洪水的回水堤马家沟堤和化工堤,以及江心太阳岛围堤和一水源、二水源围堤等共11个堤段。这些堤段经过1957年洪水抢险度讯后到1958年大规模筑堤加固,逐年填土加高,当时堤防高度4～8m,高程由上游到下游为123.0～120.8m,堤顶宽度,窄的4～10m,宽的30～50m,已形成了警戒水位118.1m,保证水位119.0m,设防水位120.3m 的40年一遇防洪标准。但是进入80年代,连年出现较大洪水,同流量下水位提高现象十分明显。1986年出现10年一遇洪水,流量与1969年相同为8500m3/s,水位却提高0.4m(119.18m～119.58m),江堤出现各种险情47处,特别是道外区,离堤100m 内的居民菜窖都普遍渗水,房内出水致使倒、拆房300多户,七道街出现管涌洞直径35cm,裂缝长30m 等险情。

夜钓黄湖

山河依旧,尤思故园。今夜独钓,我心安详。到达黄湖边后,在新修的湖堤上驻足凝望,落日西沉,偌大的湖面一眼望不到尽头,湖水安安静静地伏卧在长堤之下,那年它兴风作乱的狰狞仿佛都是久远的故事,如今钓鱼人闲适安逸地走在大堤上,微笑漾满脸庞。湖坝下的横堤有一小簇芦苇,去湖里钓鱼的人多了,从中穿梭出一条路来,分成两排的芦苇被风吹绿,又随风摇晃;野豌豆的藤蔓在它的脚下随堤漫延.

Comparison between responses of reinforced and unreinforced embankments due to road widening

The objective of this work is to compare the responses of geosynthetically-reinforced embankment and unreinforced embankment due to road widening by using the centrifuge model tests and a two-dimensional(2D) finite element(FE) model. The measured and calculated responses of the embankment and foundation exposed to road widening include the settlement,horizontal displacement,pore water pressure,and shear stresses. It is found that the road widening changed the transverse slope of the original pavement surface resulting from the nonuniform settlements. The maximum horizontal movement is found to be located at the shoulder of the original embankment. Although the difference is small,it is clearly seen that the geosynthetic reinforcement reduces the nonuniform settlements and horizontal movements due to road widening. Thus the reinforcement reduces the potential of pavement cracking and increases the stability of the embankment on soft ground in road widening.

Lateral displacement of silty clay under cement-fly ash-gravel pile-supported embankments: Analytical consideration and field evidence

Based on back analysis of lateral displacements measured in situ by using the analytical solution, a useful method for estimating stress concentration ratio of geosynthetic-reinforced and pile-supported(GRPS) embankments was proposed. In order to validate the proposed method, a full-scale high-speed railway embankment(HSRE) with four instrumented subsections over medium compressibility silty clay was constructed in three stages. The soil profile, construction procedure and monitoring of settlements and lateral displacements of the four test sections were described. The field deformation analysis results show that 1) the combined reinforcement of CFG piles and geosynthetic layer perform well in terms of reducing lateral displacements; 2) the development of lateral displacements lags behind the increase of fill load, which can be attributed to the vertical load transfer mechanism of the pile foundation; and 3) pile length has a dominant effect on the stress distribution proportion between piles and surrounding soils. The comparison between predicted and experimental results suggests that the proposed analytical solution and the back analysis-based method are capable of reasonably estimating the lateral deformation and the stress concentration ratio, respectively, if the appropriate soil elastic modulus is chosen.

五华县人大积极办理人大代表议案、建议

五华县人大把办理人大代表议案、建议作为实践"三个代表"和对人民高度负责的一件大事来抓,努力为民造福,做到领导重视,落实专人办理,使46件议案、建议较好地得到办理落实。去年,该县十一届人大四次会议收到代表议案35件,其中1件列为议案,其余34件均转作建议处理,不足10名代表提出的建议意见11件,合计46件。确定46件代表议案、建议由14个单位承办。去年8月14日,县人大常委会、县政府联合召开了承办单位负责人会议,县长张远方对办理质量、办理时限等提出了严格的要求。议案、建议交办后,各承办单位做到领导负总责,分管领导亲自抓,并指定专人负责办理。

在红色土地上播种希望——汉川市人大常委会视察促进革命老区发展条例实施掠影

汉川是一块有着光荣革命传统的红色土地。在风起云涌的革命战争年代,这里曾经是连接鄂豫皖和湘鄂西两大革命根据地的重要枢纽,留下李先念、贺龙等老一辈革命家的光辉足迹,有5000多名革命先烈为国捐躯。2014年8月29日,在《湖北省促进革命老区发展条例》颁布实施一周年之际,汉川市人大常委会部分组成人员视察了全市贯彻实施条例情况。把根留住:唤起贯彻条例原动力视察前,市人大常委会精心安排了一场别开生面的序曲——瞻仰横堤革命烈士纪念塔。
