| 摘 要： | 在桥梁工程中,墩、桩的计算长度问题一直是工程界没有定论的问题.以m法为基础,将桩的稳定分析与计算长度联系起来.通过欧拉公式,分析了桩径、埋深、土层抗力系数和墩高对摩擦桩计算长度的影响.结果表明,随着桩径、墩高的增加,摩擦桩计算长度增加;土层抗力系数对计算长度影响较小.最后给出了便于工程应用的摩擦桩计算长度系数表格.

| Abstract: | It is an uncertain problem that determining the effective length of piles in bridge construction.Based on m-method,stability analysis is adopted to determine the calculating length of piles.The influence of piles diameter,buried length of piles,resistance of soil on the side of piles and pier height to the calculating length of friction piles is studied by using Euler formula.The results present that the calcula-ting length increase with the pile diameter and pier height increasing.The resistance of soil in... |
