摘　　要：采用线弹塑性荷载传递函数 ,按桩顶沉降控制法确定深厚覆盖土层中普通桩有效桩长。对影响有效桩长的桩刚度系数等因素参数取值及荷载传递函数参数确定 ,进行了深入分析。从理论上较系统分析了各因素对普通桩有效桩长的影响 。According to the control method of top settlement of pile the effective length of common\|used piles in deep overlay soil layers is analyzed with linear elastic\|plastic load transfer function.Parameters influencing effective length such as the coefficient of pile rigidity and load\|transfer function are studied.Factors to affect the effective length of common\|used pile are analyzed by the theory and the results agree to the analytic conclusion with the elastic theory method.
