Abstract

In order to test the correctness and feasibility of high strain measured curve fitting method of pile, field tests of vertical bearing capacity of pile were carried out using prestressed concrete pipe pile. The following test results can be obtained: (1) According to the actual soil layer parameters of test sites, the relevant fitting parameters in dynamic model of pile and soil were modified; The fitting calculation programs were compiled by MATLAB, and the measured data of high strain were calculated; The calculated curves can fit well with the measured curves. (2) Compared with the static loading test results, the ultimate bearing capacity of pile of dynamic testing at two test sites was reduced by 13.03% and 11.35% respectively; The bearing capacity of pile measured by the high strain measured curve fitting method was relatively accurate. The research results can provide a theoretical basis for the design and bearing capacity testing of pile foundation.
