摘要
根据与三峡船闸高边坡下四层排水系统的优化推荐方案相对应的渗透压力,采用三维非线性有限元方法对船闸的南北高边坡岩体的位移场和应力场进行了分析,并根据位移场和屈服区确定边坡稳定的强度储备安全系数。分析表明,该排水系统的优化方案是可行的。
According to the osmotic pressure for the optimum drainage system in the high slopesof the ship lock in the Three Gorges Project, a 3-D nonlinear FEM is adopted to analyse thedisplacements and the stress fields of the south and north high slopes of the ship lock, and to findthe stability factor of safety in reservation on the basis of the displacement field and the yield area.The results indicate that the optimun design of the drainage system is practicable.
