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。
青藏公路長期處于高寒、噁劣的特殊環境中,以水害(凍土)為主要特徵的各種路基病害頻繁髮生。對青藏公路主要路基病害中的水害問題進行瞭調查,在昆崙山口至五道樑段,選取典型水害分佈點,從水文地質角度齣髮,總結瞭青藏公路的主要公路水害問題,分析瞭引起相應水害問題的水文地質機理。
청장공로장기처우고한、악렬적특수배경중,이수해(동토)위주요특정적각충로기병해빈번발생。대청장공로주요로기병해중적수해문제진행료조사,재곤륜산구지오도량단,선취전형수해분포점,종수문지질각도출발,총결료청장공로적주요공로수해문제,분석료인기상응수해문제적수문지질궤리。
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.
