橡胶粒径与掺量对橡胶砂液化性能的影响
Study on the Influence of Rubber Particle Size and Content on Liquefaction Performance of Rubber Sand Mixture
摘要
Abstract
In order to study the liquefaction characteristics of rubber sand mixtures,a new type of geotechnical filler,this study conducted hollow cylinder torsional shear tests on rubber sand mixture with different rubber particle sizes and volume contents,and the development laws of dynamic pore water pressure and shear deformation characteristics of the rubber sand mixture were investigated.The test results show that the addition of rubber particles has a significant effect on the liquefaction resist-ance of sand.In the rubber sand mixtures with less than 10％rubber content,the dynamic pore water pressure development curve of the mixture is almost the same as that of pure sand.The mixture with a rubber content of 20％-40％has more sand-rubber contact,and the liquefaction resistance increases with the rubber content,while the plastic deformation decreases gradually.The mixture with a rubber content of more than 50％does not liquefy.Under the condition of 30％rubber content,adding rubber particles smaller than the particle size of sand will enhance the liquefaction resistance of the mixture.When the rubber particle size is larger than that of sand,the mixture exhibits obvious the elastoplastic properties.Moreover,as the particle size of the rubber increases,the overall elasticity shows a down-ward trend,and its liquefaction resistance is relatively lower than that of pure sand.关键词
