摘要
本文介绍了在极高吸力工况下，介质吸力与含水率关系的测定工作，由于传统的测量方法此时的不适用性，本文研究采用保持密闭空间定湿度的饱和盐溶液方法，进行了高压实膨润土吸力－含水率关系的测定，测量结果显示，对于高压实膨润土，给定吸力情况下的最终含水率与试样初始干密度及初始含水率无关，这个结果对于研究非饱和状态下水分迁移有极其重要的意义。
Determination of relationship between suction pressure of medium and moisture ratio under very high suction is introduced in this paper. For highly compacted bentonite the said determination is conducted in this research by using the method of saturated saline solution under airtight space and definite moisture as the traditional method is improper to be used here. As indicated by the determination result the final moisture ratio of highly compacted bentonite under given suction pressure is neither influenced by the initial dry density nor by the initial moisture ratio of sample. this conclusion is very significant for the study of moisture transport under unsaturated state.
