摘要
三宝沥大桥为京珠高速公路广珠段的一座大桥,全长680m,主跨为35m预应力工字梁,基础(半幅)为4根1 2嵌岩灌注桩,单桩承载力为5200kN,针对在设计计算中存在着一部分不合理因素,分析了嵌岩桩施工质量对桩基承载力的影响,提出了对规范中嵌岩桩计算方法的相关问题。
Sanbaoli Bridge, a bridge on Guang Zhu section of Jing Zhu Express Highway, is 680 m long with a main span of 35m prestressed Ibeam. Its foundation (half width) is 4 pieces of 12 anchoredinrock castinsitu piles with a load bearing capacity of 5200 kN for each pile. In light of some unreasonable factors existed in design calculation, this paper analyzes the influence of the construction quality of anchoredinrock piles to the load bearing capacity of pile foundation. It also presents related issues on standardizing the calculation method of anchoredinrock piles.
