主体结构逆作法施工技术在某深基坑与地下结构工程中的应用

在南坪中心交通枢纽工程地下结构工程边坡支护结构施工中出现意外的情况下,果断采用主体结构逆作法施工技术,不仅保证了直立高切坡的安全,而且确保了工期目标的顺利完成,取得了比较令人满意的结果。同时,在目前的工程技术水平和施工条件下,作者对主体结构逆作法施工的一些局限性也有一定的认识,供同行探讨,以期能使逆作法施工管理水平更上一个台阶。

Application of Converse Construction of the Main Structure Technology in A Deep Foundation Project and Underground Structures

The resolute adoption of converse construction of the main structure technology achieved satisfaction when emergences happened during an underground structure engineering project slope supporting devices were in danger in the transport hub in the central area of Nanping district.This tech-nology not only ensured the security of high cliff construction but also contributed to accomplishing duration target.At the same time,concerning the pre-sent engineering technology level and execution conditions,we believe there is some understanding of a number of limitations on the reverse construction in the main structure for other engineers referrences so that the converse construction management level will be improved a level higher than before.
