摘要
结合某桥梁的荷载与组合工况,建立了该桥梁钢板桩围堰的数值分析模型,分析计算了三种工况下板桩、支撑体系及围囹的强度,并检算了支撑、基坑抗隆起和嵌固的稳定性,确保钢围堰的力学性能满足规范要求。
Combining with the loading and composite construction circumstances of some bridge, the paper establishes the numeric analysis mod-els for the steel sheet pile cofferdam, analyzes the strength of the sheet pile, supporting system, and framing scaffold, and calculates the stability of the support, and upheaval of the foundation pits and building- in , so as to meet the demands for the dynamic performance of the steel coffer-dam.
