斜坡上的建筑基础通常需要考虑其稳定性,由于邻近基坑开挖引起斜坡的任何变化都必将影响其上建筑基础的稳定安全。结合重庆市石板坡长江大桥南桥头F匝道桥下基坑开挖过程,采用传递系数法分析研究了基坑开挖、车辆离心力及桩基抗滑力对于斜坡安全系数的影响,为匝道桥的安全提供判断标准。 Building foundations on slopes usually need to consider their stability, and any changes in the slope due to the excavation of adjacent foundations will inevitably affect the stability and safety of the foundations on which they are built. Combined with the excavation process of the foundation pit of F ramp bridge in south bridge of Shibanpo Yangtze River Bridge in Chongqing, the influence factors of excavation, vehicle centrifugal force and pile sliding resistance on the slope safety factor are analyzed by the transfer coefficient method. Provide the standard of safety.
