Abstract

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.
