泡沫轻质土路基水理特性研究
Study on Water Physical Properties of Foam Light Soil Subgrade
摘要
Abstract
Due to a series of subgrade problems caused by the change of dry and wet environment,in order to study the hydraulic properties of foam light soil subgrade,unconfined compressive strength tests were carried out on specimens with different water content and different silty clay content,and the varia-tion laws of peak strength,residual strength and secant modulus E50 of foam light soil were analyzed.The results show that:(1)the peak strength,residual strength and secant modulus E50 of foam light soil de-crease with the increase of silty clay content and soaking time;(2)The dynamic modulus shows a trend of first increasing and then decreasing with the increase of water content,and the higher the content of silty clay,the smaller the dynamic modulus;(3)In order to meet the requirements of the bearing capacity of foam light soil and have less brittleness,the content of silty clay should be 24%.关键词
