【摘要】 本文对地基土横向抗力系数进行了分析与比较从而指出参数ｍ在横向受荷桩设计中的适用性。通过对大量试桩资料进行计算与分析并采用数理统计的有关方法进行统计，最后确定出具有一定可靠性指标的适用于预制钢筋混凝土桩的ｍ值取值范围。该结果已纳入新编制的《建筑桩基技术规范》。更多还原

【Abstract】 This paper analyses and compares the coefficients of lateral subgrade reaction and points out the adaptibility of parameter m in designing piles under lateral loading.A large number of test data about precast RC piles has been calculated and analyzed,and relevant method of mathematical statistics has been used to determine the parameter m. Finally, the parameters m adaptable to precast R C piles with certain reliability have been presented and this result has been adopted by the Specification of Building Pile Foundation.更多还原
