黄文熙-蒋彭年(水利水电科学研究院)终结讨论:各讨论文对水中填黄土坝土料的压箱性和孔隙压力的发生与消散的测定、整理资料及应用等方面,作出了有益的评论。兹提出答复意见如下: (一)应力应变关系在利用三轴试验来研究土的压缩性及土中起始孔隙压力及其消散方面,魏汝龙、沈珠江、盛崇文等同志认为这个方向是正确的,而且应予肯定的;但是他们认为由于三轴试验的应力条件是轴对称的,整理分析资料应该采用应力不变量,如八面体剪应力。三轴排水压缩试验所取得的试验结果改用τ_m或[τ_m/(σ_m+σ)]/tg_φ以代原文中的σ_1/σ_3作为参数。由于
Huang Wenxi-Jiang Pengnian (The Institute of Water Resources and Hydropower Research) concluded the discussion: The discussion papers have made beneficial results in measuring and collating the occurrence and dissipation of the pressure box and pore pressure of the earth filling material in the water-filled yellow earth dam. comment. The reply is hereby presented as follows: (a) Stress-Strain Relationships In the use of triaxial tests to study the compressibility of soil, and the initial pore pressure in the soil and its dissipation, Wei Xiaolong, Shen Zhujiang, and Sheng Chongwen consider that this direction is correct. , And should be affirmed; but they believe that due to the triaxial test of the stress conditions are axisymmetric, the finishing analysis data should use stress invariants, such as octahedral shear stress. The experimental results obtained by the triaxial drainage compression test were changed to τ_m or [τ_m/(σ_m+σ)]/tg_φ to use σ_1/σ_3 in the original text as a parameter. due to
