Retaining wall optimization design method based on multi-objective optimization

Abstract

The invention discloses a retaining wall optimization design method based on multi-objective optimization. The retaining wall optimization design method comprises the following steps: 1, determining function positioning; determining function positioning of a retaining wall in an engineering project through early-stage data, and determining a function objective function and variables related to thefunction objective function; 2, determining a function sequence; optimizing weight distribution, and conducting function priority sorting on the positioned functions through an expert investigation method according to external conditions such as site evaluation and external loads; 3, determining a judgment condition; and 4, carrying out optimization judgment until all functions are met. The invention aims to provide the retaining wall optimization design method based on multi-objective optimization, so as to solve many problems existing in a retaining wall optimization design method in the prior art, and achieve the purposes of reducing subjective factor interference, ensuring result accuracy and improving optimization efficiency.

Description

technical field

[0001] The invention relates to the field of foundations, in particular to an optimal design method for retaining walls based on multi-objective optimization. Background technique

[0002] In the prior art, the design methods of the retaining wall are mainly divided into the following two types: 1) apply the design atlas; 2) try the algorithm;

[0003] The algorithm process of the retaining wall test is as follows: the first step is to select the base position; the second step is to draw up the section form and size of the wall body, analyze the load and combination of the retaining wall, and carry out the checking calculation of the retaining wall; the third step is to check that the calculation result does not meet the specifications If the requirements or the safety factor is too large, re-draw the section form and size of the wall, and repeat the above design steps until the requirements are just met. Among them, the retaining wall checking calculation i...
