摘　　要：对孟加拉达舍尔甘地进厂道路跨河桥梁桩基础分别采用了引孔锤击沉管混凝土灌注桩和当地常用的钻孔混凝土灌注桩。在相同的地质条件下,对单桩和群桩承载力、沉降值、群桩效应系数进行了设计,比较了两种桩型具有的优缺点,分析了两种桩基在两倍工作荷载作用下沉降的设计值和试验值。对选定的桩型进行了单桩承载力试验,结果表明:桩基的设计和施工质量均满足相关技术规范要求,桩基施工质量较好。The pile foundation of the bridge crossing the river on the access road to Dasherkandi in Bangladesh is adopting pilot hole hammer driven cast-in-place pile and bored concrete pile commonly used locally.Under the same geological conditions,the bearing capacity,settlement value and pile group effect coefficient of single pile and pile group are designed.The advantages and disadvantages of the two pile types are compared,and the design value and test value of settlement of two types of pile foundation under double working load are analyzed.The single pile bearing capacity of the selected pile type is tested,and the results show that the design and construction quality of pile foundation meet the requirements of relevant technical specifications,and the construction quality of pile foundation is good.
