摘要
以沿海地区某桥梁工程为例 ,说明了软基中桥头路基对附近桥墩及桩基的影响。计算时采用了能够考虑桩土体系参数及侧向土压力沿深度任意变化情况的新方法 ,滑面以上部分桩身受到的侧压力根据沈珠江 ( 1 990 )基于散体极限平衡理论推导的公式计算得到 。
The effect of embankment constructed on soft clay for nearby piled pier of bridge is illuminated by an example of damaged piled pier in somewhere of coastal area in this paper.A new method is presented to calculated the displacement and bending moment along the pile and pier which can account the parameters of layered siol and the arbitrary lateral force into consideration firstly.Then,an existing method based on the limited equilibrium theory developed by SHEN Zhu jiang(1990) is adopted to calculated the lateral force acting on pile section above the critical surface.It shows that the calculated result and analysis make more clear the reason of damaged piled pier.
