摘要
确定土的抗剪强度和强度指标的方法应分为有效应力法、总应力法和固结应力法等三种 ,而不能仅仅分为前两种方法。强调土的固结不排水剪阻角的定义应该表示其不排水强度随着剪前固结应力增长而提高的规律 ,指出目前用来整理直剪和单剪试验结果的常规方法 。
It is pointed out at first that the approaches to determine the shear strength and strength parameter of soils must be classified into effective stress method, total stress method and consolidation stress method instead of only the former two methods. Then the definition of the angle of consolidated undrained shearing resistance for normally consolidated soil is emphasized that it should represent the rate of increase of undrained strength with increasing consolidation stress before shearing, so that the conventional method used to interpret the results of direct and simple shear test is practically feasible.
