摘　　要：针对地表水沿断裂及地裂缝带入渗引起的地表不均匀差异沉降变形对公路路基路面的影响,在综合分析地表水入渗作用机理的基础上,运用大型通用岩土数值分析软件MIDAS/GTS,研究了地裂缝、活断层环境下地表水入渗对公路路基路面的影响效应。研究结果表明,路基底面在公路重力作用下将随着地表一起下沉,路基底面的变形曲线与地面的沉降曲线基本一致,路面及路基底面的受力状态主要由地表不均匀沉降曲线控制。In order to study the change of surface differential settlement when surface water infil- trate fissure to suhgrade and pavement structure, based on in-situ permeability test and finite element software MIDAS/GTS, the influence was analyzed and tested. The results show that the basement will sink together with road surface on the gravity of highway, and its deformation is identical with the ground settlement curve, the stress state of the road is under control of uneven surface subsidence curve. 1 tab, 8 figs, 16 refs
