摘要
本文根据原型和接近于原型的群桩横向承载力的系统试验结果,分析了横向荷载下桩的相互影响效应、桩顶约束效应、承台侧抗效应及基底摩阻效应,在此基础上提出了群桩横向承载力的分项综合效应系数计算法,并以试验结果进行了验证,说明用该法计算群桩横向承载力简便可行。
Series of prototype and models very close to prototype were tested for lateral bearing capacity of pile group. Effects of interaction among piles, restraint of pile top, lateral resistance of cap and friction of cap bottom were analyzed. Method of evaluation of comprehensive effect coefficient for lateral bearing capacity of pile group are presented. The comparison between calculated and measured values shows that this method is feasible and simple.
