HSS 模型在软土地区水闸地基基础设计中的研究

摘要

This paper describes the theoretical basis of Hardening Soil Model and Hardening Soil Small-Model in the geotechnical finite element analysis.Discuss the choice of parameters.A Shanghai sluicewhich located in the South Bank of Hangzhou Bay sluice as an example, use HS-Model and HSS-Model calculated by FEA, comparedthe results with the measured data.The calculation results show that the HSS model simulation results and monitoring results of the process of engineering construction is more consist-ent, which meansthe HSS-Model can better side load, the interaction between the foundation and the upper structure, can opti-mize the design of the sluice engineering guide complex foundation.%阐释了近年来岩土有限元分析中常用的土体本构模型HS模型及HSS模型的理论依据，探讨其参数选择办法，以某位于上海市杭州湾南岸水闸为例，同时采用HS模型与HSS模型进行了有限元分析计算，并与实测监测数据展开对比，通过计算结果对比表明HSS模型模拟结果与工程建设过程中监测成果更为吻合，说明HSS模型可以更好的模拟边载、地基基础及上部结构之间相互作用，可以指导水闸工程复杂地基基础的优化设计。
