摘要
基于静力触探(Cone Penetration Test,CPT)和孔压静力触探(Piezocone Penetration Test,CPTU)测试参数预测桩基竖向承载力方法的相关文献,对CPT/CPTU预测桩基竖向承载力的方法进行归纳分析,对比分析了CPT/CPTU测试与静载荷试验、高应变动测法、标贯试验,归纳了不同测试方法的优势和不足.工程实例表明CPTU方法预测桩基承载力最接近静载荷测试结果.CPTU测试方法考虑了孔隙水压力的影响,具有精度高、数据连续、可重复测试、成本低的特点,值得推广和应用.
Based on the relevant literature on the methods for predicting the vertical bearing capacity of pile foundation by CPT and CPTU test parameters,the methods for predicting the vertical bearing capacity of pile foundation by CPT/CPTU were summarized and analyzed.CPT/CPTU test,static load test,high strain change test and standard penetration test were compared and analyzed.The advantages and disadvantages of different test methods were summarized.The engineering example shows that the CPTU method predicts the bearing capacity closest to the static load test results.The CPTU test method takes into account the influence of pore water pressure,and has the characteristics of high precision,continuous data,repeatable test and low cost,which is worthy of promotion and application.
