重力式墩柱挡土墙

Earth Retaining wall Depended on Gravity of Pier-stud

介绍一种新型重力式挡墙,墙身结构简单、受力明确,充分发挥了重心后移的效果,提高了自稳定性,具有良好的经济性。采用逆作法施工,解决了普通重力式挡墙施工中原有土体卸载变形的不稳定问题,适合于施工作业面受限制及建筑密集地区使用。通过实例介绍重力式墩柱挡墙的设计、施工流程与工法。

A new type of gravity-retaining-wall was introduced,which provided with simple structure,directly load transferring and economical cost,and utilized the effect of gravity center moving backward to increase the self-stability.The method of contrary construction was used to settle the problem of instability existing in earth load-off deformation caused by the construction of ordinary gravity-retaining-wall.This type of gravity-retaining-wall was fit for application in dense area of building and the construction place were limited.Finally,the paper presented the design,construction procedure and construction method of pier-stud gravity-retaining-wall through a project example.
