贝宁科托努立交桥是中国政府对外援助的成套项目工程,建设场址位于沼泽地带,地质条件极差,为避免日后项目场址范围内不规范的河道清淤、开挖、临建、违法堆载等行为给桥梁带来安全隐患,同时实现形象美观的目的,决定对立交桥范围内进行河道整治及绿化工程,主要讨论计算参数及工后不确定填土堆载对桥梁桩基安全影响的敏感性分析,可为类似特殊地质条件下桥梁受影响范围内的安全防护及软土处理方案提供借鉴。
The Cotonou Overpass in Benin is a complete set of foreign aid project by the Chinese government. The construction site is located in a swamp zone with extremely poor geological conditions. In order to avoid irregular river dredging, excavation, temporary construction and illegal construction within the scope of the project site in future, Such as pile loading and other acts to bring security risks to the bridge, while achieving the purpose of aesthetic image, decided to overpass within the scope of river regulation and afforestation projects, mainly discuss the calculation parameters and post-mortem underfill embankment on the safety impact of the pile foundation Sensitivity analysis can provide reference for the safety protection and soft soil treatment schemes within the bridge affected by special geological conditions.
