摘要:
采用在粉质黏土中掺和锯末的方法配制模型土,通过降低模型土模量来降低土体的相似畸变。设计研制了2个土箱,用以模拟盆地边界以及自由场地边界。通过大型振动台试验,对比盆地与自由场地的实验数据,对盆地的聚焦效应和边缘效应进行较为深入的研究。结果表明:盆地效应对地震动有着明显的放大作用,且在聚焦效应和边缘效应区域内放大显著。
Abstract:
To reduce soil analogy distortion, a kind of soil model with low modulus was made by mixing sawdust with silty clay.Then, two soil-boxes were designed to separately simulate the boundaries of basin and free field.By comparing test data from shaking table tests, for the two fields above,a detailed research on focusing effect and edge effect was completed.Results showed that the earthquake response was obviously amplified with the basin field,especially in the areas with focusing effect and edge effect.
