摘要断层地质构造严重影响采空区高速公路路基的稳定性，针对断层构造采空区复杂条件，利用更能反映实际问题的三维数值模拟方法，运用非线性弹塑性有限元技术，分析矿区开采、交通动荷载等引起断层地质构造采空区“活化”，研究采空区“活化”、断层地质构造对采空区路基失稳的影响，研究复杂条件下高填路基病害机制、变形和地基不稳定性，探讨复杂条件下修筑高填路基而出现的变形与失稳问题，为寻找防治路基路面出现不连续变形、沉陷，确定合理设计提供理论依据。

Abstract：Faultage geological structure will influence stability of road bed seriously which passes through waste area，thesis study that faultage geological structure“activate”influenced by coal mining to effect stability of road bed in waste area，which uses nonlinear plasticity finite element technology，to study faultage“activate”，distortion of road bed and instability of road bed，seeking a method to prevent and cure discontinuous deformation and sink of road bed surface，to offer technological basis for rational design.

Key words： mining engineering faultage geological structure traffic loads waste area activation high embankment deformation instability evolution analysis
