郑西客运专线渑池至灵宝段地质综合勘察技术

研究目的:郑西客专线为中国第一批建设的无砟轨道客运专线,其中渑池至灵宝段为越岭段,地形起伏大,沿线分布煤矿采空区、滑坡等不良地质;分布人工弃土、深厚湿陷性黄土层等特殊岩土。对彻底查清沿线地质条件,取得合理岩土参数对客运专线建设具重要作用。研究方法:本段地质勘察过程以系统论和控制论的方法为基础,制定合理的勘察方案;合理选择勘探测试方法,对重要对象采用多种方法对比勘察。本文总结了本段地质勘察采用的方法及综合运用技术。研究结果:本段地质勘察工作已于2005年结束,勘察成果通过了相关审查鉴定。研究结论:郑西客专线开工建设至今已近二年,经施工验证,地质勘察成果与实际地质条件相当吻合。

Geological Integrated Survey Technology for the Section between Mianchi and Lingbao of Zhengzhou - Xi'an Railway Passenger Dedicated Line

Research purposes: Zhengzhou-Xi'an Railway Passenger Dedicated Line is the first ballastless track railway built in China and the section between Mianchi and Lingbao of it is a summit section with the unfavourable geological conditions of big ups and downs landform,coal mine's goafs,waste soils and deep collapsible loess along the line.The geological conditions can be made clear and the parameters of rock soil can be obtained by adopting geological integrated survey technologies,which has significance to construction of the line.Research methods:Based on the system theory and control theory,the rational survey program is worked out,the rational survey method is selected,and many methods are adopted for the important objects to make comparisons.In this paper,the method and technologies used for surveying geological conditions in this section are summed up.Research results:The surveying work was complete in 2005 and the survey achievement has been appraised.Research conclusions:The construction of about two years shows the result of geological survey conforms to the real geological conditions.
