锚固工程设计多采用极限平衡理论，以临界滑落面作为设计前程。推求临界滑落面时，采取以非圆弧滑落面为对象进行坡面稳定分析，在滑动体中，取一微小单元，解析受力条件，进行力平衡及力矩平衡计算。引入地形参数、物理参数，用动态设计法求得最小安全系数，确定锚固力大小及实施位置。研究结果表明，施工前后为固定滑落面所需锚固力不尽相同，为确保安全系数，要加大锚固力，同时临界滑落面的位置比施工前加深，采用Ｓｐｅａｃｅｒ法和动态设计法综合设计，方法可行。
Anchorage engineering design to use limit equilibrium theory to the critical slip surface as a design future. When the critical slip surface is deduced, the slope stability analysis is performed on the non-arc sliding surface. In the sliding body, a small unit is taken and the stress conditions are analyzed to calculate the force balance and moment balance. The introduction of topographic parameters and physical parameters, the dynamic design method to obtain the minimum safety factor to determine the size of the anchoring force and the implementation of the position. The results show that the anchoring forces needed to fix the sliding surface before and after construction are not the same. To ensure the safety factor, the anchoring force should be increased and the critical slip surface should be deepened before construction. Speacer method and dynamic design method are used to design the anchorage force. Method is feasible.
