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 provide judge criterion for safety of the ring bridge.
