荷载作用引起砂土渗透性变化的试验研究
Experimental study of influence of compressive stress on water permeability of sands soils
摘要
Abstract
Considering the practice of embankment construction, the experimental device and experiment method to prepare experimental samples with different compactnesses to measure water permeability of sands soils or clay under compressive load changes was manufactured. According to the measurement of variations of water permeability under compressive load or unload in different compactnesses, the rule of water permeability of sand soil was revealed due to be influenced by different compressive loads and different compactnesses. It is shown that the compressive load and compactness both influence the water permeability of the sand soil greatly; but the factor of compressive load influences, its water permeability more greatly. Especially for the low compactness soil, the influence of the load on the permeability is very obvious.关键词
