摘要
通过调查统计广州地铁多个深基坑设计文件,对地铁基坑设计计算中的若干问题进行探讨,包括采用弹性地基梁时的经典和弹性法、全量和增量法、水土分算和合算等计算方法,并对目前土体与围护结构共同作用的有限元法常用的本构模型进行了分析。结合基坑计算实例,分析计算结果,比较各种算法的优缺点,为地铁基坑的设计计算提供参考。
Through the survey of Guangzhou subway deep foundation pit design documents, some problems about calculation in the design of subway foundation pit are discussed, including comparison between classical method and elastic method when using elastic foundation beam calculation method, total method and incremental method, water and soil calculating separately and combined method and so on, also to analyze current common constitutive models used in soil and retaining structure coordinately working finite element method analysis. Some foundation pit calculation examples are elaborated, calculation results is analyzed, and the advantages and disadvantages of various calculation methods is compared, which can provide a reference for metro pit design and calculation.
