    Abstract
  • Combined with the engineering example of soft rock socketed pile in a high-rise building, the vertical bearing capacity of a single pile determined by rock uniaxial compressive strength test, in-situ plate load test, and single pile static load test was compared and analyzed. The results show that the standard value of the vertical ultimate bearing capacity of a single pile determined by the plate load test method is 1.51 times that of the rock uniaxial compressive strength method. According to the current local standard safety factor K, the characteristic value of the bearing capacity of a single pile determined by the plate load test has not been improved; The characteristic value of single pile bearing capacity obtained by the single pile static load method is 3.12 times that obtained by the rock uniaxial compressive strength method. According to the analysis results, the bearing capacity of a single pile determined by the rock uniaxial compressive strength method is conservative, and it is suggested to consider the influence of the confining pressure constraint effect. When the rock foundation load test method is used for calculation, it is suggested to adjust the value of the Chongqing local standard safety factor K.
