摘　　要：在我国岩土工程实践中，工程师们对以下３个问题一直有争论：１）在采用总应力法确定粘性土土体的抗剪强度时，如何正确选择抗剪强度指标；２）在试验室如何正确测定不排水强度指标；３）在根据固结不排水强度指标确定土体抗剪强度时，如何正确操作。本文指出他们争论的焦点所在以及正确的做法。Dispute has been continuing between Chinese geotechnical engineers on the following issues: 1) How to select appropri- ate total shear strength parameters for the determination of Shear strength of cohesive soil mass; 2) How to measure the undr- ained shear strength parameters in laboratory; 3) How to determine the shear strength of soil mass based on the consolidated undrained strength envelope. This paper describes the points of dispute and the correct method of operating.
