| 摘 要： | 与单圆盾构工法相比，双圆盾构工法有其独特的施工技术要求，其影响地表沉降的因素更为复杂。根据上海轨道交通六号线双圆盾构区间段地表沉降实测数据的统计分析，总结了地表沉降槽的形态特征，提出了沉降槽宽度范围的估算公式。结合双圆盾构区间段的工程实践，进一步探讨了与地表沉降相关的双圆盾构施工参数的取值问题。

| Abstract: | Compared with single circle shield tunneling,the DOT(Double-O-Tube) has its particular construction techniques and more complex factors which influence the settlement development.Based on the statistics of measured settlement due to the DOT tunneling in Shanghai metro line No.6,this study summarized the characters of settlement troughs' configuration.An estimated formula was presented to predict the influenced extent.Referred to the tunneling practice,the study discussed the scale of some construction parameters related to the ground settlement. |
