摘要

依托上海轨道交通M6线9标双圆盾构区间隧道工程，选取试验段对双圆盾构施工参数进行了敏感性分析。试验过程中调整土舱压力、盾尾注浆量、推进速度等施工参数，动态监测双圆盾构施工引起的横向、纵向深层土体沉降规律。所得结论对于双圆盾构施工参数优化、减小环境土工影响具有一定借鉴意义。

Abstract

Based on the section tunnel construction of M6 rail transit project No.Ⅸ bid in Shanghai

the sensitivity analysis of construction parameters were carried out. During the construction

the parameters of cabin pressure

grout volume of shield tail

advance velocity were rectified designedly. The layered settlement of transverse and longitudinal sections induced by the construction of double-O-tube shield (DOT) in soft clay region was monitored continuously in-situ. The conclusion can be as reference for optimizing of the construction parameters

lessening the extent of environmental influence of soil engineering.
