长春地区白垩系泥岩地层地铁施工中地质风险及技术措施研究

摘要

The article makes a systematic research on basic geological features of Cretaceous mudstone by analysis of mineral composition,micro electric microscopy,physical and mechanical property test,expansion and slaking test of different weathering degree mudstone,wave velocity,resistivity test,anlysizing geological risk probably existing in subway construction in Cretaceous mudstone,putting forward corresponding technical measures and suggestions,providing a geological reference for subway design and construction.%通过矿物成分分析、电镜微观结构分析、物理力学性质试验、不同风化程度泥岩的膨胀和崩解试验、波速、电阻率测试等手段,对长春地区白垩系泥岩的基本地质特征进行系统研究,分析在此类地层中地铁施工可能存在的地质风险,提出相应的技术措施,为地铁建设工程问题分析及计算提供工程地质依据.
