摘要

近年来，我国修建的长大隧道经常遭遇高压地下水作用，隧道围岩中渗流场与应力场存在着耦合作用。对于高水压隧道而言，按照耦合过程中围岩的破坏情况，可以分为变形过程中的耦合作用和破裂过程中的耦合作用。如果只考虑隧道开挖后围岩的变形，则渗流-应力耦合作用可概括为天然充填物变形、无充填裂隙接触变形、裂隙时效变形和人工充填物变形等模式。考虑隧道开挖过程中围岩的破坏，则渗流-应力耦合作用可以概括为卸荷和水力劈裂裂隙模式。在隧道二次应力场中，变形和破裂过程相伴而生，耦合作用模式的建立可以为隧道设计、施工及地质灾害防治提供明确的概念模型和参考依据。

Abstract

High pressure groundwater environment becomes one of the key problems for tunnel construction under complicated hydro-geological conditions in China. The seepage field of surrounding rock is coupled with stress field. According to the failure course of surrounding rock

the coupling mode is divided into 2 types: deformation mode and failure mode. In the course of excavation

if ignoring the failure

the seepage-stress coupling mode includes fill compressed mode in filled crack

wall touching mode in crack without filling

time-depending mode and grout-filled mode. If considering failure

the seepage-stress coupling mode includes failure mode caused by excavation and failure mode under high water pressure. Different geological and hydro-geological conditions and different excavation courses will lead to different coupling courses

the establishment of coupling mode will provide concept model and support for design

construction and disaster prevention.
