海区输电杆塔桩基的随机波浪力模拟研究
Simulation on the Random Wave Forces of Pile Foundation of Transmission Towers in Coastal Areas
【摘要】 基于随机波浪力谱分析法,以改良P-M谱为目标谱,采用线性叠加法对输电线路基础的波浪荷载进行了模拟和参数研究。结果表明,重现期、水深和柱体直径等因素均对塔基波浪荷载产生了较为显著的影响。
【Abstract】 The stochastic wave force spectrum was utilized and the modified P-M spectrum was taken as the target spectrum.The wave loads on the tower were simulated using the linear superposition method and parametric study were carried out.The results indicate that the effects of various factors, such as return periods, water depth and column diameter, on the wave loads of tower foundation are obvious.
