陈愈炯同志对笔者所写的“沥青混凝土心墙土石坝的应力应变分析”一文(以下简称原文)发表了很好的意见。在讨论中提及根据土样浸水前后的压缩曲线,就“认为在三轴试验中,也只需分别测定干的和湿试样的应力-应变曲线,就可看出浸水的影响”。但我们认为,仅对干态和饱和试样的应力-应变曲线进行比较,是不能反映湿化变形的。湿化变形应从干态土料的应力-应变曲线,在到达某一应力状态后,并控制应力状态不变情况下,浸水饱和所测得的变形值。按照这个思路,我们在10cm直径三轴仪上,进
Comrade Chen Yuxi expressed very good opinions on the article “Stress and Strain Analysis of Asphalt-Concrete Core Earth-Rock Dams” written by the author (hereinafter referred to as the original). In the discussion, referring to the compression curve before and after water immersion in soil samples, “it is considered that in a triaxial test, the stress-strain curves of dry and wet specimens can be determined separately, and the effect of flooding can be seen.” However, we believe that comparing the stress-strain curves of dry and saturated specimens alone does not reflect the wet deformation. The wetting deformation should be from the stress-strain curve of the dry earth material, and after reaching a certain stress state and controlling the state of the stress state, the deformation value measured by the saturation of the inundation water. According to this line of thought, we proceed on a 10cm diameter triaxial apparatus.
