改建铁路青藏线西宁至格尔木段增建第二线工程地质灾害危险性评估

ASSESSMENT OF THREATENING ENGINEERING GEOHAZARDS ON THE SECTION BETWEEN XINING AND GOLMUD AS PART OF THE SECOND PHASE OF THE QINGHAI-TIBET RAILWAY PROJECT.

青藏铁路西宁至格尔木段增建第二线工程作为青藏铁路的一部分,线路全长约763.2 km,沿线地质构造复杂和地层岩性岩相变化大,线路穿越多个构造单元,地质灾害发育;本文对沿线区域内地质环境条件进行了详细论述,对地质灾害的类型、分布进行了阐述,对工程建设可能引发或加剧和工程建设本身可能遭受地质灾害的危险性进行了预测评估和综合评估,提出了防治地质灾害的措施及建议。

Construction of the railway from Xining to Golmud is an additional second-line engineering as a part of the Qinghai-Tibet railway, with a whole length 763.2km. There are complex geological structures and lithology facies variation passing through several tectonic units, easily causing geological hazards; In this paper, the regional geo-environment conditions and possible types of geological disasters were discussed in detail , and distribution are set forth, for the construction and engineering may trigger or exacerbate the building itself may be subjected to risk of geological disasters in the forecasting evaluation and integrated assessment, proposed measures for prevention and control of geological disasters and recommendations.
