摘要
青藏公路长期处于高寒、恶劣的特殊环境中,以水害(冻土)为主要特征的各种路基病害频繁发生。对青藏公路主要路基病害中的水害问题进行了调查,在昆仑山口至五道梁段,选取典型水害分布点,从水文地质角度出发,总结了青藏公路的主要公路水害问题,分析了引起相应水害问题的水文地质机理。
As located at pretty high altitude and in seriously bad environment, Qinghai-Tibet Highway suffers to various subgrade diseases characterized by water disasters and permafrost to a great extent. The water disasters herein are investigated in such manners that their typical localities between Kunlun Mountain Pass to Wudaoliang are selected and then, from the viewpoint of hydrogeology, the disasters are generalized and the related hydrogeological mechanism are analyzed.
