船台滑道下含软弱层岸坡的空间稳定分析

ANALYSIS OF THE STABILITY OF SLOPE WITH THICK SOFT LAYER UNDER SHIP-BIULDING PLANE

芜湖江东船厂新建船台滑道位于有较厚软弱土层的岸坡上。本文采用三维有限元和刚体极限平衡理论结合的方法分析岸坡稳定 ,对不同潜在滑动面进行探索 ,求解最小安全系数及相应滑动面位置。分析结果已在施工实践中得到证实。

A new ship building paltform will be constructed on the slope with thick soft layer in Wuhu Jiangdong ship building factory. We used the FEM method and rigid limit equilibrium theory to analyze the stability of this slope. The minimum safety factor and corresponding potential sliding surface were given to each stage of ship building. The results had been verified in the construction.
