摘　　要：介绍了FLAC-2D,根据基坑工程具体实例,采用FLAC-2D对基坑开挖及其支护结构状态进行计算和分析;并模拟了在未进行支护条件下的基坑开挖,得出了基坑土体在支护和未支护条件下,土体的应力状态、位移等值线图、位移矢量图、最终沉降量和结构受力。计算结果也证明了支护结构设计的合理性,对工程设计及施工分别起到了验证和预测的作用。This paper introduced FLAC-2D, based on an example of pit construction, calculated and analysed the excavation and the state of reinforcement structure; meanwhile, simulated the excavation with support in contrast to that without support, and obtained： stress state, displacement contours, displacement vectors, ultimate subsidence and the beating of the structure. The calculation results proved that the design of structure is correct, respectively playing the role of validation and prognosis for the design and construction.
