摘要

层间错动带存在的普遍性，给世界上许多工程带来了岩体稳定性问题和地质灾害。通过对因层间错动带导致工程岩体结构变形失效或破坏的实例进行归纳总结，采用岩体结构控制理论的观点将含层间错动带的岩体的破坏模式分为拉裂破坏、掉块和层间剪切滑移破坏3大类。以此为基础，提出剪切力学模型是层间错动带力学模型研究的重点。对层间错动带剪切力学特性的现有试验方法和建模理论进行评述，并根据现有的研究基础，提出屈服面蠕变模型是当前层间错动带剪切蠕变模型的较好选择。

Abstract

Because of existence worldwide of interlayer staggered zone

there have been many engineering rock mass stability problems and geological disasters occurred over the world. In this paper

some cases of distortion failure or destruction of engineering rock mass structure induced by interlayer staggered zone are summarized. Rock mass structure controlling theory is adopted to categorize the failure modes of rock mass with staggered zone into tension crack failure

block-fall and interfacial shear slip failure. After that

it is shown that shear strength model is the main point when modeling for the mechanical behavior of interlayer staggered zone. A deep review of the existing test methods and the modeling theory for its shear behavior shows that the elasto-viscoplastic model is the fundamental constitutive model for describing the mechanical behavior of interlayer staggered zone.
