| 摘 要： | 通过对某梁板式高桩码头实例进行建模分析,采用p-y曲线法考虑桩土相互作用,研究不同加载模式对高桩码头pushover分析的影响。分析对比5种加载模式的受力、位移变化等特性,并与时程法计算结果进行对比。结果表明,桩基屈服顺序主要受到桩的斜度和倾斜方向的影响,均匀分布加载模式反映了结构弹塑性阶段的上限。对时程法计算结果综合分析表明,集中力加载模式和SRSS模式与时程分析结果符合较好。

| Abstract: | Analyzing some examples of pile-supported wharf modeling,we adopt thep-y curve method to study the soil-pile interaction and discuss the effect of load patterns for pushover analysis of pile-supported wharf.The stresses and the displacement under different loading patterns are analyzed and compared.In addition,the results are compared to that calculated by the time history method.Results show that the yield sequence of pile foundation is mainly affected by the slope of pile and the inclined direction.The uniform distribution loading pattern represents respectively the maximum values calculated by the pushover analysis for aseismic calculation.The result of the concentrated force loading pattern and the SRSS loading pattern are very close to that by the time history method. |
