Taking No.6 high and steep slope design of the second phase extension project of Chongqing port orchard work zone for example,we introduce the way of combining topography,geology and land occupation condition to carry out stability analysis on high and steep reinforcement fill slope using the method of Bishop on the basis of limit equilibrium theory,and accordingly make economical and practical design scheme.The design scheme can be confirmed after the security is validated by centrifugal model test.Finally,we examine the safety and reliability of the design scheme by monitoring measurement results in the construction period,to serve as reference for high and steep fill slope treatment in harbor land area engineering and road engineering.
