钢管桩静力拔桩侧摩阻力的计算对比分析

Comparison and Analysis of Side Friction Resistance of Static Pulling Piles for Steel-pipe Piles

对于钢管桩拔桩侧摩阻力的计算有多种计算方法,具有代表性的两种就是APIRP2A的计算方法和国内规范法,为了更好地了解这两种计算方法的特点和差别,通过对不同的工况分别采用API-RP2A的计算方法和国内规范法计算,计算对比分析两者的区别以及产生区别的原因,同时简要分析两种计算方法的优缺点。

There are many calculation methods for the calculation of side friction resistance of steel - pipe pile pulling, and the two representative methods are the calculation method of API - RP 2A and the domestic standard method. In order to better understand the characteristics and diffrences of the two calculation methods, in this paper we calculate the side friction resistance in dirt）rent conditions with two dirt）rent methods, which are API - RP 2A calculation method and domestic standard method. The difference between the two calculation methods and the reasons for the dift）rence are compared and analyzed, at the same time, the advantages and disadvantages of the two methods are briefly analyzed.
