浅谈高应变曲线拟合法在预应力管桩中的应用

Application of High Strain Curve Fitting Method in Pre-stressed Pipe Piles

文中结合福州市闽侯县工程实例,对比同一根桩采用动静两种方法测得的极限承载力,对高应变曲线拟合法在预应力管桩中的应用进行可靠度分析。通过数据对比分析可以得出,高应变曲线拟合法测得的结果相对误差较小、可靠度较高,在预应力管桩中较为适用。

Based on an engineering example in Minhou County,Fuzhou City,this article compares the ultimate bearing capacity of the same pile measured using both dynamic and static methods,and conducts a reliability analysis of the application of high strain curve fiting method in prestressed pipe piles.Through comparative analysis of data,it can be concluded that the results obtained by the high strain curve fiting method have relatively small errors and high reliability,and are more applicable in prestressed pipe piles.
