摘    要:根据堤岸结构分期施工的特点,以有限单元法为分析手段,取用土体为Mohr-Coulomb模型,基于弹塑性算法,分析模拟了堤岸分期施工的整个过程.同时作为对比,将分期施工的堤岸转化为等效荷载作用于地基土体,进行了有限元分析计算.两种方式的计算结果表明,采用分期施工模拟的方式更接近于实际,其结果用于设计和施工更为安全.

关 键 词:分期施工  Mohr-Coulomb模型  弹塑性  有限元

Abstract:According to the property of the construction of the bank, the soil is regarded as the Mohr-Coulomb model. And with the elastic-plastic algorithm, the whole procedure of the construction of the bank at different stage is simulated with the method of FEM. And for the comparison, the bank constructing at different stages is regarded as the equivalent load acted on the foundation. With this method, the computation based on the FEM is accomplished. The results of these two ways show that the method based on the construction at different stage is near to the reality and is more safe to be used for the design and construction.
Keywords:construction at different stage  Mohr-Coulomb model  elastic-plastic  FEM
