某工程TRD的实施难点及施工效果分析

Analysis of Difficulties in Implementation of TRD in A Project and Construction Effect

随着“大、深”方向建筑基坑工程的发展,当下深基坑施工技术所面临的问题越来越突出。TRD工法是一种新的水泥土搅拌墙施工方法,比常见的三轴搅拌桩防水幕墙更深,对深基坑支护结构具有很好的防水性和适应性。结合某工程实例,介绍了TRD工法实施的难点,分析了施工效果。通过对一些监测数据的解释,进一步验证了TRD实施的可行性和可靠性。

With the development of the foundation pit engineering in the “big and deep” direction,the problems faced by the construction technology of the deep foundation pit are becoming more and more prominent. The TRD method is a new cement-soil mixing wall construction method,which is deeper than the common three-axis mixing pile waterproof curtain wall,and has good waterproofness and adaptability to the deep foundation pit supporting structure. Combined with a project example,the difficulties of TRD construction method are introduced,and the construction effect is analyzed. The feasibility and reliability of TRD implementation is further verified by interpretation of some monitoring data.
