Influencing factors and control measures of excavation on adjacent bridge foundation based on analytic

Shuangxi FENG, Huayang LEI, Yongfeng WAN, Haiyan JIN, Jun HAN

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 2,   Pages 461-477 doi: 10.1007/s11709-021-0705-0

Abstract: Many uncertain factors in the excavation process may lead to excessive lateral displacement or over-limitedIt was found that the excavation depth and the distance between the foundation pit and the bridge foundationpit.Furthermore, the lateral displacement of the bridge pile foundation, the internal force of the piles,and the settlement of the soil surrounding the pile foundation were emphatically analyzed.
