Analysis about the Linited Units of the Zhaoyuan Songhua River Huge Bridge

桩穿过不同性质的土层将上部结构荷载传递给桩周和桩底土层,形成复杂的桩土共同作用系统。目前,研究荷载传递的方法有弹性理论法、有限元法和传递函数法等。本章通过有限元法,结合岩土体结构特征,分析本工程上部荷载传递过程中应力及位移的变化,为桩侧摩阻力的取值奠定基础。

The pile passes distinct nature earth straturms lcads the upper composition transmission gives circuit and pile subsoil straturm,takes shape complex pile earth affecting the system together.At the moment,researching the means loading the transmission possess resilience theory law and finite element method and transfer function law and so on.This section is by means of the finite element method,and unites the crag earth part of the body architectural feature,and analyses that stress is loaded in the transmission process in project upper part and the bit shift alternation,and in the interest of the pile side scrapeeing,obstruction geing value is settleed the base.
