曲线桥下斜坡受邻近基坑开挖的影响研究

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。

Research on influence of a djacent excavation on slope stability under curve bridge

Any minor structural change of slope stability caused by adjacent excavation might result in serious distortion of the above architecture;therefore,slope foundation stability should be put to first priority in bridge construction.In light of the slope excavation under the F ring bridge of the Chongqing Shibanpo Changjiang Bridge,by means of transfer coefficient methods,the influences of adjacent excavation,vehicle centrifugal force and pile anti-slide force on the slope safety factor are analyzed so as to p...
