This paper introduces the design from the branch watershed(Hubei-Chongqing boundary) of the backbone of Shanghai-Chengdu National Expressway to semi-slope bridge(Huandanlian Bridge) on expressway in Zhong County,and proposes some rough understandings for the design of semi-slope bridges in mountainous areas as a source of reference for.
介绍沪蓉国道主干线支线分水岭至忠县高速公路半坡桥(环担脸大桥)的设计情况,对山区半坡桥设计提出一些粗浅认识,供同仁参考。
By utilization of mathematical statistics theory,the general expression of soluting the bearing capacity of slope bridge foundation is fitted out in the paper,through regression analysis of each influencing factor,including the pile diameter,pile length,pile material,rock mass property,bridge foundation position and gradient of slope,etc.
利用数理统计理论,通过对影响斜坡桥基承载力的各因素,包括桩径、桩长、桩身材料、岩体特性、桥基位置及斜坡坡度等进行回归分析,拟合出求解斜坡桥基承载力的一般表达式,对斜坡桥基的设计具有一定的指导意义。
