摘　　要：结合工程实例,选用PLAXIS有限元软件,采用理论分析和有限元数值模拟相结合的方法,研究了嵌岩桩嵌岩深度的确定问题,并对试验桩进行了有限元模拟分析,通过对比分析结果与现场试桩结果,验证了模型的可靠性。In this paper,the method to determine the depth of rock-socketed pile is studied by the theoretical analysis and finite element numerical simulation using PLAXIS finite element software,companied by the analysis of specific engineering practices. To verify the reliability of the model,the finite element simulation result of the test piles was compared with those of the field test piles.
