Method for verifying pile end corrosion limestone stability and pile foundation bearing capacity of cast-in-place pile foundation based on karst development area
The invention relates to a method for verifying pile end corrosion limestone stability and pile foundation bearing capacity of a cast-in-place pile foundation based on a karst development area. The method comprises the following steps of S1, exploration investigation and sampling; s2, analyzing a sample indoor test to determine the corrosion performance and physical and mechanical parameters of the limestone; s3, monitoring the underground water level in combination with hydrogeological conditions; s4, performing numerical simulation by using the data to evaluate the stability of the limestone; s5, pile foundation structure parameters are determined according to results, engineering design and specifications, and loads are estimated; s6, an instrument is arranged to measure the pile side resistance change, the friction angle and the bearing capacity are calculated, and the pile foundation bearing capacity is evaluated; s7, a static load test instrument is arranged to apply loads, response and deformation characteristics are monitored, and the pile foundation stability is evaluated; and S8, analyzing the interaction of limestone corrosion on the pile soil to correct the bearing capacity so as to determine the bearing capacity of the pile foundation. According to the method, multiple data acquisition methods are integrated, the reliability of the verification result is improved, and the bearing capacity of the pile foundation is evaluated more accurately by analyzing the interaction between limestone corrosion and pile soil.
