摘要

传统双侧壁导坑法存在施工工序多、施工速度慢、闭合时间长等不足。以深圳市红棉路隧道工程为背景，对传统工法进行改进，并采用数值方法重点分析改进的双侧壁导坑法的安全性。主要研究结论如下： 1）提出改进的双侧壁导坑法； 2）在合适的地层采用改进的双侧壁导坑法，能够满足地表沉降、结构受力、施工安全等各项隧道施工技术要求； 3）应用改进的双侧壁导坑法能够产生良好的技术效益和经济效益。

Abstract

Conventional double side drift method has such disadvantages as complex construction sequence, low construction speed and long time for support ring forming. In this paper, the conventional double side drift method is optimized, and the construction safety of the optimized double side drift method is analyzed by means of numerical simulation, on basis of the engineering practice of Hongmianlu tunnel in Shenzhen. Conclusions drawn are as follows: 1) Optimized double side drift method is proposed; 2) When optimized double side drift method is used in proper geological conditions, the technical requirements for the ground surface settlement, structure forcing and construction safety can be met; 3) Optimized double side drift method can result in good technical and economical efficiency.

Key words： tunnel; optimized double side drift method; construction safety analysis
