紧邻防汛墙基坑的方案及施工实践

Design of foundation pit adjacent to flood control wall

随着城市的快速发展,城市交通网络越来越拥挤,高架桥或立交桥逐渐兴起,埋置桥墩的基坑常靠近河流岸边防汛墙,这给基坑的设计及施工带来了较大的难度。以上海某紧邻防汛墙基坑工程为例,探究了紧邻防汛墙基坑实施过程中的一般原理和注意事项。基于不同类别的基坑,研究了基坑变形及内力情况,结果对紧邻防汛墙基坑工程理论及实践有一定的借鉴意义。

With the rapid development of the city,the urban traffic network is becoming more and more crowded,and viaduct or overpass become more and more. The pit buried pier are often near the flood control wall along the river,which brings great difficulty to the design of foundation pit. In this paper,with a certain pit near the flood control wall in Shanghai,the general principles and matters needing attention in the design of foundation pit adjacent to the flood prevention wall are explored. Based on the different types of pits,the deformation and internal force are researched. As the results show,the method of design has the deep influence on the engineering and theoretical research of foundation pit near the flood control wall.
