【摘要】 首先综述了国内外单桩、群桩基础、承台及桩周土的总体研究现状,在此基础上,设计并进行了竖向荷载下单桩和群桩基础承载性能的室内试验,通过测量桩身应变及在单桩桩顶和群桩承台上布置百分表,研究分析了单桩及两种不同角桩桩距条件下群桩基础的承载性能和沉降变形特征.更多还原

【Abstract】 The general researching status of single pile,pile group foundation,pile cap and the soil around pile at home and abroad is summarized,then the indoor test of the bearing capacity of single pile and pile group foundation under vertical load is designed and conducted.The bearing capacity and settlement character of single pile and pile group foundation of two different corner-pile spacing are studied and analyzed by measuring the strain along the pile and arranging dial indicators on the top of single pile and pile cap of pile group foundation.更多还原
