摘　　要：基于52个点的地基载荷试验数据与对应试验点附近岩块的单轴抗压强度试验数据的对比分析,对深圳地区花岗岩地基的承载力进行了研究探讨。综合考虑试验场地实测的地基承载力与剪切波波速值,给出了按剪切波波速值初步估计深圳地区花岗岩地基承载力特征值的建议值范围,对类似工程项目有一定指导和借鉴意义。Based on the comparative analysis of the 52-point foundation load test data and the uniaxial compressive strength test data of the rock blocks near the corresponding test points,the bearing capacity of the granite foundation in Shenzhen area was studied and discussed.Comprehensively considering the measured foundation bearing capacity and shear wave velocity of the test site,the recommended value range for preliminary estimation of the characteristic value of the bearing capacity of the granite foundation in Shenzhen area based on the shear wave velocity is given.This paper has certain guidance and reference significance for similar projects.
