利用CPTU对淤泥质黏土工程性质的评价
Evaluation of engineering characteristics of mucky day using static cone penetration tests
摘要
Abstract
Taking the mucky clay on a river beach as an example, the in-situ tests on pore-pressure dissipation of the mucky clay at different depths were performed by use of the static cone penetration (CPTU) tests, and the consolidation coefficient was obtained. It was compared with that from the laboratory tests, indicating that the consolidation coefficient determined by the CPTU tests was 10 to 100 times higher that measured in the laboratory. The method for estimating the undrained shear strength by means of the CPTU tests was introduced. Its results were compared with those from the vane shear tests. The applicability of those methods for the mucky soil was evaluated, and the scope of their empirical coefficients was determined.关键词
