泡沫轻质土路堤稳定性分析及材料参数控制标准
Foam lightweight soil embankment stability analysis and controlstandard of material parameters
摘要
Abstract
In order to analyze the factors of foam lightweight soil embankment stability, calculation model using ANSYS, based on strength reduction fem to study the influences of density, cohesion and internal friction angle of foam lightweight soil on foam lightweight soil embankment stability, then the sensitivity analysis to each factor is carried out, and the stability of the foam lightweight soil embankment and the common soil embankment is compared.The results show that density and cohesion of foam lightweight soil are two important factors of embankment stability;when the design density of the foamed lightweight soil is less than 6 kg/m3, the cohesion is above 60 kPa, the safety factor of embankment with different heights is greater than common soil embankment, and can meet the requirement of 16 m high embankment stability.The control standard of cohesion for foam lightweight soil of different height embankment under different density(600, 800, 1 100 kg/m3) was proposed.关键词
