沈珠江(南京水利科学研究院):原文从摩尔-库伦强度理论及毕晓普的孔隙压力公式出发推导出粘土的不排水强度,即破坏时的应力状态是初始应力状态及加荷时主应力方向偏转角的函数。该文对理解室内及现场各种剪切试验的结果很有意义。但作者对有关的假设和前提论述不够,本讨论准备就这方面补充几点看法。为简单起见,下面叙述中也象原文一样忽略中主应力的影响。
Shen Zhujiang (Nanjing Hydraulic Research Institute): The original deduce the undrained strength of clay from the Mohr-Coulomb strength theory and Bishop’s pore pressure formula, that is, the stress state at the time of failure is the initial stress state and the deflection of principal stress at the time of loading. The function of the angle. This article makes sense for understanding the results of various shear tests in the room and in the field. However, the author’s discussion of the relevant assumptions and premise is not enough. This discussion is prepared to add a few points of view in this regard. For the sake of simplicity, the following description ignores the influence of the principal stress as the original text.
