PHC-钢管组合桩高应变检测修正方法
Modification method for high strain test of PHC-steel compound piles
摘要
Abstract
To solve the problem of the ultimate bearing capacity in design and the difficulty in high strain test for nontraditional PHC-steel compound(PSC)piles,high strain test and vertical static load test were carried out.Three PSCs made of PHC and steel piles were designed with different length ratios.Pile-sinking was performed using the hammering method,and the vertical bearing capacity of the PSC was obtained by in situ high strain test and vertical static load test.Then,a modification for the high strain measured curve fitting method was proposed by theoretical analysis.The results show that the vertical bearing capacity of the PSCs measured by the high strain measured curve fitting method is higher than that from the static load tests while the results computed by the proposed modification method were in consistent with the static load tests.Therefore,the modification method can be applied to the measurement of the vertical bearing capacity of the PSCs.关键词
