摘要
本文采用电镜、Ｘ射线和常规滴定法，对川渝东部侏罗系中下统的粘性岩土进行了粘粒矿物组成、化学成分及胀缩率的测定。并确定为低膨胀性粘性土，为防治蠕移变形、减轻其危害提供了科学和理论依据。
n this paper, by employing of electronic microscope, X rays and common titrimetric methods to test clay particle mineral composition, chemical composition and swelling shrinking ratio of clayey soil weathered from the early and middle Jurassic strata in the eastern parts of Sichuan province and Chongqing city. And the clayey soils are finally determind to possess lower swelling ratio. This determination provides scientific and theoritical bases for the protection of creep hazard and its reduction.
