紧邻防汛墙基坑防汛安全影响研究

Study on Influence of Foundation Pit on Safety of Adjacent Flood Control Wall

随着经济的迅速发展,上海市城区内地下建筑物的数量逐渐增加,规模也逐步增大。地下基坑的开挖对于河道防汛墙的安全将造成影响,从而也引出了一个必须考虑的防汛安全问题。该文基于陆家嘴南滨江三角绿地车库工程项目的分析和总结,将地下工程施工对于防汛墙的影响的实际监测值与计算值进行对比,分析如何控制基坑围护结构周边防汛墙实际变形,避免引起防汛墙的损害。

With the fast development of the economy,the quantity of underground constructions in the downtown of Shanghai is increasingly increased,and the scale also becomes larger.The excavation of underground foundation pit will affect the safety of river flood control walls.Thereby,a safety issue of flood control has to be considered.Based on the analysis and summary of Lujiazui South Binjiang Triangle Greenbelt Garage project,the article contrasts the actual monitoring value and the calculation value of the influences of the underground engineering constructions on the flood control wall,and analyzes how to control the practical deformation of the flood control wall surrounding the retaining structure of foundation pit and how to avoid the damage of the flood control walls.
