| 摘 要： | 从监测指标和监测范围两个方面对钱江隧道盾构进出洞加固体稳定性的实时判别进行了研究,即首先在分析板块理论和弹塑性静力学理论的基础上,提出能实时反映盾构进出洞加固体稳定性的监测项目,包括水土压力P及其相应的稳定性评价指标K 0、K sf,而后采用理论分析和试验研究加固体的破坏模式,在此基础上,提出加固体实时监测点布置方案。通过监测点的合理布置,监测加固体所受水土压力P,计算K 0、K sf,可实现加固体稳定性的实时评价。

| Abstract: | How to timely identify cemented soil stability for Qianjiang tunnel breakthrough is discussed in terms of monitoring indices and monitoring range.Firstly,based on the plate theory and elastoplasticity theory,the water and earth pressures on the cemented soil are presented which can timely identify the cemented soil stability during shield tunnelling breakthrough as well as two indices,.Then,a failure mode for the cemented soil is put forward on the basis of existing failure modes to underlie the observation... |
