膨胀土胀缩特性试验研究
摘要:以南(宁)友(谊关)膨胀土大量的室内试验为基础,研究了膨胀土胀缩时程曲线特征,寻找膨胀土膨胀和收缩曲线的异同点,探求了土的初始含水量、干密度与膨胀变形量的定量关系等。
Abstract:Based on lots of laboratory tests of Nan(ning)-You(yiguan) expansive soils, the relationship between shrink-swell and time of expansive soils is researched. The similarities and differences between shrink and swell are found. The quantitative correlation between deformation magnitude with different original water content and dry densities is explored.
