摘要:
在确保支护结构和周边环境稳定的前提下,如何优选支护结构方案,降低造价,对深基坑支护设计、施工具有重要意义。以常州市轨道交通1号线控制中心基坑工程为依托,围绕技术、工期、造价、施工质量与安全四个一级评价指标和工程地质条件等14个二级评价指标构成的评价指标体系,对三种初选方案的评价进行权重汇总,得出综合评价值,选出最优支护方案。该基坑工程选取的最优方案为:“桩锚”支护和排桩+内支撑,局部被动区加固; 选AB段进行支护结构计算,分别用等值梁法、天汉软件验算了支护结构稳定性,其结果满足规范要求。
Abstract:
In the design of deep foundation pit support, how to optimize the support structure and reduce the cost is of great practical significance to the design and construction of deep foundation pit support under the premise of ensuring the stability of the support structure and the surrounding environment. The paper is based on the foundation pit project of the control center of Changzhou Rail Transit Line 1. It focuses on an evaluation index system which is composed of four primary evaluation indicators such as technology, construction period, cost, construction quality and safety, and fourteen secondary indicators including engineering geological conditions. The weights of the three preliminary selection schemes are summed up so as to obtain the comprehensive evaluation value, from which the optimal support scheme is selected. The optimal scheme of the foundation pit project is "pile anchor" support and row pile + internal support, and local passive area reinforcement; The stability of the support structure was calculated by using the equivalent Liangfa and Tianhan software, and the results meet the requirements of the specification.
