【摘要】 对单桩受力变形分析的荷载传递法进行了修正,并在此基础上提出软岩嵌岩桩与岩土相互作用比较完善的有限元模拟方法,在接触单元中引进传递函数,用无限元处理边界问题,考虑了沉渣的影响等,并编制了相应程序,将计算与实测结果进行了比较,对南宁泥质砂岩嵌岩桩进行了单桩承载计算机模拟试验。结果表明用该程序对软岩嵌岩桩承载进行计算是符合实际的,模拟结果对软岩嵌岩桩的施工和设计有指导意义。更多还原

【Abstract】 The method of load transmission for deformation analysis of single pile is revised. On this basis,a perfected FEM simulation method is presented which can simulate the interaction between a rock-socked pile and rock or soil in soft rock. The transmission function is introduced in contact elements and the boundary conditions are treated by infinite elements. The influence of sediment is also considered. A computer program has been developed. We calculated and compared results with measured data,then used them to simulate a rock-socked pile in mud-sandstone around Nanning region. The results show that it is rational and feasible to use this program to simulate and analyze a single pile in soft rock. The simulated results give guidelines for construction and design of soft rock-socked piles.更多还原
