摘要
利用强夯法和常规击实法压实非饱和黄土时在压密过程中的相似性,分别采用上述两种方法制备土样来试验研究强夯压实黄土的工程力学性质。试验结果表明:压实黄土的压缩模量、回弹模量、粘聚力及内摩擦角随击实功的增大而增大;强夯压实黄土的干密度普遍较击实黄土低,但其压缩模量和强度较室内击实黄土明显地大。
By using two methods as a dynamic compaction method and a normal compaction method separately, the soil samples are fabricated to research the engineering mechanics property of the dynamic compaction loess. The test results show that the compression modulus, modulus of resilience, cohesion and angle of internal friction of the compaction loess increase with the compactive effort. The dry density of the dynamic compaction loess is lower than that of the indoor compaction loess, hut the compression modulus and intension of the dynamic compaction loess are larger than those of the indoor compaction loess.
