软岩嵌岩桩承载力的计算与试验对比分析
Comparison and Analysis ofCalculation and Test about BearingCapacity of Rock-Socketed Pilein Soft Rock Area
摘要:
在福建沿海地区许多重要建筑物都是以软岩作为其桩基持力层,本文依托某高层建筑的工程情况,对该工程中具有代表性的6根软岩嵌岩桩,按照JGJ94-2008《建筑桩基技术规范》、GB5007-2011《建筑地基基础设计规范》来计算其单桩竖向承载力,并进行了现场荷载试验,对计算和试验结果进行对比分析,得出了有意义的结论,为同类工程提供参考。
Abstract:
Many important buildings in coastal areas of Fujian are soft rock as its pile foundation bearing layer. Based on engineering geological conditions of a tall building, for six typical rock-socketed piles in soft rock area, according to Technical Code for Building Pile Foundation (JGJ94-2008) and Design Code for Building Foundation (GB5007-2011), this paper calculates vertical bearing capacity of single pile, and the load tests are carried out. The calculation and test results are compared and analyzed, and some useful conclusions are drawn. These conclusions will provide references for similar projects.
