摘要/Abstract

摘要： 软岩是重大交通、水电、矿山等工程建设中经常遇到的复杂介质,高地应力作用下软岩地下工程很容易产生围岩大变形,不仅对施工安全造成影响,而且还会造成建设工期和成本的迅速增加。软岩大变形已成为我国交通、水利、深部资源开发等工程领域亟待解决的重大课题。本研究以引大济湟隧道掘进机(tunnel boring machine, TBM)挤压大变形导致的管片错台为例,通过对现场监测成果的反演分析,系统研究挤压大变形不同错台的修复与控制方法,本研究成果对其他膨胀泥岩卡机事故脱困以及管片错台的工程具有指导意义。

Abstract: Soft rock is a complex medium often encountered in rock engineering of major transportation, hydropower, mining engineering construction, squeezing or large deformation is commonly accounted in high in situ stress soft rock underground engineering, which not only affects the construction safety, but also prolongs the construction period and increases the cost. The disaster of large deformation has become a major issue to solve urgently in the field of transportation, water conservancy and deep resources development in China. From the example of Datong River into Huangshui River TBM extrusion segment dislocation caused by the large deformation, repair and control method of large deformation dislocation was suggested from back analysis of field measurement. The results had guiding significance for other expansive mudstone jamming accident and engineering segment dislocation of the turnaround.

Key words: reinforcement, dislocation, soft rock, squeezing deformation, segment
