高桩码头溶洞桩承载力设计探讨OA
Design of Pile Bearing Capacity of High Pile Wharf in Karst Area
结合长江中游岩溶地区二根不同情况的桩基自平衡试验和应力测试结果,对桩的荷载传递特性进行了详细的对比分析,分析结果表明,溶洞高度范围内的桩侧阻力尺寸效应系数几乎为零,桩端阻力与溶洞大小、尺寸无关.在计算溶洞嵌岩桩轴向承载力时,端阻力尺寸效应系数仍按规范规定取值,侧摩阻力尺寸效应系数需考虑现场实际.
Based on the self-balancing test and stress test of two piles in different conditions that were driven into karst cave in the middle reach of Yangtze River, the load transfer characteristics of the above two piles were fully compared and analyzed. The analysis results showed that the size effect coefficient of pile side friction was almost zero within the height range of karst cave, and the pile tip resistance has no correlation with the size of karst cave. …查看全部>>
