超深基坑地下连续墙施工的关键技术

Continous Diaphragm Wall's key Technology in Extre-deep Foundation Ditch

虽然地下连续墙在我国的发展已有将近50年的历史,但随着基坑规模和深度的不断扩大,出现了很多新的问题,旧的施工技术无法处理。为解决这些新困难、新问题,必须创新。本文通过地下连续墙在润扬长江大桥北锚碇基础工程中的应用,就其在此工程中出现的问题进行了介绍。

Continous diaphragm wall have been applied for nearly 50 yeats in China, while many new problems have advented, which couldnt be solved with old construction technology, with the broadening of the scale of foundation ditches. So it is necessary to make innovationsto solve all these new problems. The thesis has researched the advented problems in the project of continous diaphragm wall, which is applied in north anchorage foundation of RUNYANG Yangtse River large bridge.
