Study on Cementation of Particle Analysis Test by Clay Densimeter Method
摘要
Abstract
In order to solve the problem of cementation in some analysis test of clay densitometer method,the reasons of the cementation formation are analyzed.Firstly,the improved AS method and GB method are tested with uncemented clay to verify the feasibility of the improved AS method.Then the im-proved AS method is applied to cemented clay.The test results show that the improved AS method has good dispersion effect on cemented clay,which can better solve the cemented problem of particle analysis by clay densimeter method.And the test process is simpler and more efficient than GB method,which can be applied to particle analysis test of densimeter method.In addition,in order to evaluate the error caused by different test methods in the same project,we explore the comparison of adding and reducing soil quali-ty with GB method and improved AS method.The results show that the improved AS particle size distri-bution curve are located above those from mass-adjusted GB variants,and the particle size distribution curve is closer to the improved AS method.关键词
