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。
In bridge engineering, the calculation of the length of piers and piles has always been a problem that the engineering community has not decided yet. Based on the m-method, the stability analysis of the pile is related to the calculated length. Based on the Euler formula, the influence of pile diameter, depth, coefficient of soil resistance and pier height on the calculation length of friction pile is analyzed. The results show that with the increase of pile diameter and pier height, the calculation length of friction pile increases. The resistance coefficient of soil layer has little influence on the calculation length. Finally, the table of calculating the length coefficient of friction pile for engineering application is given.
