采用三维连续介质快速拉格朗日法(FLAC~(3D))对某电厂灌注桩的竖向承载及沉降特性进行了数值模拟分析,并与静载荷竖向承载特性试验及桩身轴力实测结果进行了对比,两者互相补充和相互验证。结果表明:FLAC~(3D)数值模拟对本工程具很好的适用性。
The vertical bearing and settlement characteristics of cast-in-site piles using a three-dimensional continuous medium fast Lagrangian method (FLAC ~ (3D)) were numerically simulated and analyzed. The results were compared with those of static load and vertical load test The results are compared, the two complement each other and mutual verification. The results show that FLAC 3D numerical simulation has good applicability to this project.
