摘要

摘要: 针对土遗址锚固工程需求，提出了一种基于期望函数的锚固参数组合优化方法.该方法通过对锚固长度、锚孔直径等参数的组合优化,获得了最大锚固力与最小遗址伤害的良好平衡.试验设计为全因子试验，利用响应面方法构建分析模型，而后将统计中的期望函数法引入锚固参数优化中，建立了多重目标响应指标与锚固参数水平的关系.研究结果表明：当分别满足锚固力最大化和遗址伤害最小化目标时，相应的锚固参数取值间存在冲突；多重响应优化能够确定目标响应需求下锚固参数的可行域范围，方便工程设计人员根据实际工程条件对锚固参数进行可视化取值.

Abstract: Aimed at the needs for anchoring engineering in rammed earth sites, a composite optimization method for anchorage parameters based on desirability functions was proposed. The main purpose of the method is to obtain a good balance between the maximum anchoring force and the minimum site damage through optimization of the combination of anchor lengths and anchor hole diameters. The full factorial design was used in the experiment, and the response surface method was applied to build the analysis model. Then the desirability function in statistics was introduced into the optimization of anchor parameters, and the relationship between the multiobjective response and the anchoring parameter level was established. The results show that, when the anchoring force maximization and the site damage minimization goals are respectively satisfied, there will be a conflict between the corresponding anchoring parameters. The multiobjective response optimization can determine the feasible ranges of the anchoring parameters under the goal of response demand, which is convenient for engineering designers to visualize the anchoring parameters according to the actual engineering conditions.
