Abstract
With consolidated undrained triaxial shear test, the consolidated undrained shear characteristics of soft cement-soil in Bangkok under high water content is studied. As a result, it is found that when the cement ~ontent is less than 10 %, the cement-soil is in the state of slight over-consolidation or normal consolidation stress; when the cement content is equal to or larger than 10 %, this soil assumes the state of typical over- consolidation stress, and in this case, the lateral pressure has little influence on the strength of the cement-soil which is affected by the water content to a larger extent; however, in case of the cement content less than 10 %, the strength of the cement-soil is directly proportional to the cement content and lateral pressure. At the same time, the empirical function relation between triaxial consolidated undrained peak shear strength of the 28-days-curing cement-soil under high water content and the ratio of the water content to the cement content is predicted.关键词
