Abstract

Abstract

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.
