摘要
基于极限平衡理论的瑞典法和简化的Bishop算法,是计算边坡抗滑稳定安全系数最有效和最直接的方法。对比较均匀的边坡,采用圆弧滑裂面假设,可使用简单的模式搜索法自动搜索出边坡的最小安全系数和与之相对应的临界滑裂面的位置。用极限平衡方法分析了海洋红中心渔港防波堤在施工阶段和使用阶段的抗滑稳定性,表明了该方法在实际工程中应用的有效性。
Based on limit equilibrium, the Fellenius and simplified Bishop methods which can determine the factor of safety in slope stability are the most direct and powerful methods. For an even slope, when a circular failure surface is applied, a simple model searching method is presented to search for the minimal safety factor freely. The method can simultaneously deter- mine the minimum safety factor and the corresponding most dangerous slip surface. In this paper, the above method is used to analyze the anti - sliding stability of Hai Yang Hong breakwater. The analytical results show that it is feasible and efficient for practical engineering.
