软土地基中负摩阻影响下桩基承载力的简化计算

A simple calculation on the carrying capacity of the pile in soft soil influenced by negative skin friction

以汕梅高速公路段下穿泰山路跨线桥及泰山路互通立交桥的北延建设工程为背景,分析评估新建下穿道路对已有桥梁桩基的承载力和沉降影响,提出了一套软土地基下考虑负摩阻影响的桩基承载力和沉降的简化计算过程及方法。分析结果为下穿的北延道路建设提供了科学依据,并可为以后同类地质条件下穿道路的施工和改建提供参考。

Taking north extension highway crossing under Taishan road overpass bridge and Taishan road interchange bridge as the engineering background, this paper analyzed the influence of the overpass road on the carrying capacity and settlement of piles of built bridge and presented a simple calculation method of the carrying capacity 如d settlement of the pile irifluenced by negative skin friction. Thus thes^ entific basis for the construction of north extension highway and offered more reference for the construction of underpass road under the same geo-logical condition.
