摘要
根据波动分析理论,改进了CAPWAPC波动方程拟合分析法。可以考虑土塞对沉桩的影响,用来分析模拟打桩过程中任意时刻桩身的沉降量。分别建立了三种管桩桩内土塞计算模型来模拟土塞作用机理;并编制了相应的计算程序。通过比较三种土塞模型的计算结果与实际海洋工程实测数据,最后得到工程中与实际吻合最好的土塞模型。
According to wave theory, Improved CAPWAPC wave equation method, which can consider the im- pact of the pile driving by soil plug, used to analysis the state of motion of the pile at anytime. Established three pipe pile soil plug computational model to simulate the soil plug mechanism of action, and prepared the correspond- ing calculation program. By comparing the calculation results of three soil plug model and the engineering measured data, the best soil plug model is got.
