数值模拟法找自平衡法试桩自平衡点位置应用研究

Study on Application of Numerical Simulation Method to Find Self-Balancing Position of Oile Test

随着我国经济水平的提高和交通建设的飞速发展,我国的桥梁工程设计施工能力也有了大幅度提升,自平衡试桩法就是应用信号处理技术在不破坏基桩的情况下的一种新型试桩方法。对于不同的桩长及桩径在不同的地质、上部荷载的情况下自平衡荷载箱的安装位置不同,这就需要预估一个桩基的自平衡点位置,本文用数值模拟法进行荷载箱位置即自平衡点的寻找,为自平衡试桩法的应用就较好的参考。

With the improvement of China's economic level and the rapid development of traffic construction,China's bridge engineering design and construction capacity has been greatly improved.The self-balanced pile test method is a new type ofthe test that applies signal processing technology without damaging the foundation piles.Pile method.For different pile lengths and pile diameters under different geological conditions and upper loads,the installation position of the self-balancing load box is different.This requires an estimation of the position of the self-balancing point of a pile foundation.This paper uses a numerical simulation method to determine the position of the load box.The search for the self-balance point is a good reference for the application of the self-balanced pile test method.
