地裂缝活动对Q3残积古土壤物理力学性质的影响
Influence of Ground Fissure Activity on Physical and Mechanical Properties of Q3 Residual Paleosol
摘要
Abstract
The results of the conventional geotechnical test on the undisturbed sampling of Q3 residual paleosol layer at the Jin Hutuo's trial trench of Chang'an ground fissure show that moisture content and porosity ratio are smaller on both sides of ground fissure compared with that of fracture zone, density and dry density are higher on both sides of ground fissure compared with that of the fracture zone, variation of compression modulus is not obvious on the both sides of main ground fissure. Variation of liquid limit and plastic limit are not evident on the south side of the main ground fissure while they are great on the north side of the main ground fissure. Compression modulus on the south side of secondary ground fissure is great compared with that of fracture zone and it is not obvious on the north side of secondary ground fissure. Liquid limit and plastic limit are smaller on both sides of secondary ground fissure compared with fracture zone. The test results can be used as basis for research on affecting width of the fracture zone.关键词
