摘要
采用响应面法进行了群桩基础在船撞作用下的结构静力可靠度分析。正常使用极限状态方程是基于承台横桥向位移建立的,承载能力极限状态方程是基于单桩和桥塔截面的抗压/弯强度建立的。最后进行了群桩基础结构可靠指标的敏感性因素分析,指出影响群桩基础船撞静力可靠度的主要随机因素。
Static reliability analysis is carried out for the pile group foundation under ship collision by response surface method(RSM). The normal use limit state equation is set up based on the transverse displacement of base slab, and the carrying capacity limit state equation is set up based on the bending and compression strengths of the single pile and pylon section. Finally, the article analyzes the sensibility factor of structural reliable indexes of pile group foundation, and points out the influence of the main random factors on static reliability of pile group foundation under ship collision.
