摘要
地质条件复杂的长江等大型穿越工程、鄂西山区岩溶隧道群、滑坡和岩溶塌陷等地质灾害是川气东送管道工程建设中遇到的地质难题。勘察中通过有针对性地应用工程物探、原位测试、水文实验等勘察手段,解决了长江等大型穿越复杂岩土界面和野三河大型跨越的地基稳定性等问题,查明了深埋隧道等控制性工程中的构造破碎带、岩溶特征等地质灾害的地质技术难题,提高了隧道围岩分级的准确率;通过地质灾害排查和不良地质专题勘察,为复杂地质条件下川气东送管道工程的设计和施工提供了可靠岩土参数和依据。
Geological disasters complex geological conditions across the Yangtze River and other large projects,karst mountainous area of western tunnel group, landslides and karst collapse and so is East Gas Transmission Pipeline Construction geological problems encountered in the survey by a targeted application of geophysical prospecting situ testing, hydrology experiment investigation means to solve the Yangtze River and other large complex across the interface foundation geotechnical stability across large and wild rivers and other issues, to identify the long tunnel deep control projects like tectonic fracture zone, karst geological characteristics of the technical problems of geological disasters. Through the investigation of geological disasters and adverse geological thematic survey, geotechnical parameters and to provide reliable basis for the design and construction of the pipeline to Sichuan-to-East Gas under complicated geological conditions.
