摘要
深入分析了岩溶区嵌岩桩的承载机理及变形特性,在此基础上,针对桩端下伏溶洞情况,结合岩石统计损伤理论,提出了一种新的确定岩溶区嵌岩桩竖向承载力的方法,并采用修正的Mohr—Coulomb强度理论导出相应的计算公式,可全面考虑岩层各种不良因素的影响。
Based on an analysis on the failure mechanism and deformation characteristics, a new method for determining the vertical bearing capacity of rock-socked piles with solution caverns underneath in karst ar()eas is proposed. The statistic damage theory for rock was used in the development of the method. In addition, formulations with considerations of various adverse conditions in rock strata are derived with modified Mohr-Coulomb theory.
