| 摘 要： | 通过野外实地调查发现,青藏工程走廊昆仑山口-清水河段发育的主要地质灾害隐患点有活断层儒移引起路基位错;活断裂作为导水通道,使冰丘穿刺路基;河岸坍塌导致铁路桥墩外露;铁路工程排水沟渗漏,铁路路基两侧水动力条件发生变化,导致铁路路基发生管涌;冻土冬季冻胀,夏季融沉导致路基裂缝、道路翻浆、管道变形;风力堆积作用导致青藏铁路护坡局部沙淤;风力吹蚀导致格拉输油管线外露。综合分析认为,青藏工程走廊昆仑山口-清水河段环境地质问题的产生是自然和人为因素复合作用的结果,应点、线、面结合考虑,综合治理。

| Abstract: | Through field investigations,we found that the hidden geological disasters area along Qinghai-Tibet Project Corridor include shifting subgrade,punctured subgrade by ice pings,exposed railway piers;railway embankment piping,foundation cracks barsting and runddy,roads,pipeline deformation,sand deposition at railway slopes;abd exposed pipeline.Through the comprehensive analysis,we hsld the basic causes of the geological disasters risks are active structure and poor hydrogeology conditions. |
