盾构施工扰动地层的再固结沉降分析

Re-consolidation Settlement Analysis of Disturbed Soil during Shield Driving

通过实测数据的统计分析,对盾构施工引起扰动土体的再固结沉降进行研究和讨论,初步提出从实测数据处理中得到再固结沉降量的方法,得到盾构隧道施工扰动地层再固结沉降的历时关系。

Based on the statistic analysis of measured data,the re-consolidation settlement of soil disturbed in shield construction is studied and discussed.This article preliminarily proposes that re-consolidation set- tlement volume can be deduced from the actual data so as to get the relationship between time and re- consolidation settlement during shield tunneling.
