桩锚支护设计中单支点位置优化的探讨

Discussion on optimization of single supporting point position in stake anchor bracing design

针对桩锚支护结构设计中支点位置的优选问题,以一个具体工程为实例,分别采用等值梁和极限平衡两种方法与多目标优化设计方法相结合进行计算。结果表明:最佳的支点位置与上述两种桩锚支护结构计算方法的选择无关。结合该工程实例,利用等值梁和极限平衡两种方法计算出的最佳支点位置的确定值为4.65m和4.57m。

For optimization of supporting point position in stake anchor bracing design, taking a detailed project as an example, the authors use a method to calculate that equivalent beam and multiple target optimization design are combined with limiting equilibrium and multiple target optimization design. The results indicate that the optimum supporting point position is independent of the two methods mentioned above in stake anchor bracing design. The method introduced in this paper shows the definite values of supporting point positions as 4.65 m and 4.57 m.
