摘要
在抗滑桩设计参数中,桩间距和截面尺寸已有较深入的探讨,而锚固段长度的确定,尤其是弹性抗滑桩锚固比的确定尚有待深入研究。为此,在建立锚固段岩石单轴抗压强度和水平地基系数的关系基础上,引入黄金分割优化算法,编制专门的计算程序进行锚固比优化设计,以实现满足加固后稳定性要求,侧应力复核及构造配筋等要求的前提下,达到抗滑桩单桩费用最低的优化目的。最后结合三峡库区某工程实例,表明该方法具有较好的工程应用价值。
The interval and cross section in the parameters of the anti-slide pile design have been discussed. But the anchorage rate of the pile, especially the elastic stabilizing pile, still needs to be further researched. Therefore, based on the analysis of the relationship between uniaxial compressive strength and horizontal foundation coefficient of the anchorage section rock, the golden section method and computer programming method are introduced to solve this problem. Special computing software is developed to complete the optimal design for anti-slide pile anchorage rate. In this way, the optimal aim with the lowest project charge and enough safety coefficients can be achieved. Finally, the application to landslide instance in the Three Gorges Reservoir Area shows that the optimum design method is quite economical, and it is important for the anti-slide pile design and practical application.
