基于波动方程的液压锤打桩参数标定研究
Parameter calibration of hydraulic hammer pile driving based on wave equation
摘要
Abstract
Accurate prediction of the pile penetration process is of great significance for offshore wind power and large-scale pile foundation engineering.Therefore,based on the one-dimensional wave equation and the finite difference method,a numerical analysis model for pile driving is established by integrating the dynamic characteristics of the pile,hammer,and surrounding soil,and the mass and stiffness of the hydraulic hammer are calibrated accordingly.By simulating the pile driving process from an offshore wind farm in the South China Sea,the development pattern of blow counts with penetration depth is investigated and compared with field measurements.The results indicate that the program can stably capture the dynamic response during the pile penetration process,and the simulation results are in good agreement with the field data.The rapid computation and parameter calibration method based on the numerical pile driving analysis model provides reliable technical support for hammer performance evaluation,construction parameter optimization,and engineering applications.关键词
