摘要
研究了土体硬化模型(HS模型)与小应变土体硬化模型(HSS模型)的理论依据,并以偏压基坑的工程实例为基础,对比分析两种本构模型在基坑有限元计算中的适用性,得到HSS本构模型相对HS本构模型在偏压基坑有限元分析计算中与实际监测数据更接近的结论。
Based on an engineering example of asymmetrically loaded deep excavation, the theoretical foundations of constitutive models of HS and HSS were analyzed. The contrast analysis of HS and HSS constitutive model applied in the numerical simulation of asymmetrically loaded deep excavation was studied. It is found that the deformation of the numerical simulation by HSS constitutive model is more close to monitoring data.
