Three-level optimization method for civil engineering design

Abstract

The invention belongs to the field of civil engineering construction, and relates to a three-level optimization method for civil engineering design. The method comprises the following steps of carrying out first-level system optimization, determining boundary conditions according to basic information of a project, and providing a scheme set; determining an index set and a weight set of each indexaccording to factors considered by engineering design, and calling an optimization function to select a first-level optimization design scheme through comparison; performing secondary detail optimization, wherein a secondary detail optimization scheme is determined according to a primary optimization design scheme; performing third-level dynamic inversion optimization: performing construction stepdynamic simulation and construction guidance based on the first-level optimization design scheme and the second-level detail optimization scheme; and performing parameter adjustment inverse analysisaccording to the construction information, perfecting a secondary detail optimization scheme, correcting construction steps according to the perfected secondary detail optimization scheme, and performing dynamic simulation to guide on-site construction again. The method is high in applicability, and design can be optimized from the whole to the local and from the static state to the dynamic statein an all-direction mode by using an optimization system in engineering.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to an optimal design method in construction engineering. Background technique [0002] With the rapid development of our country's infrastructure, new techniques and new technologies are constantly emerging, and engineering design tends to be complicated and diversified. The level of engineering design directly determines the progress, cost, quality and even social impact of the project. In order to improve the design quality, various optimization methods have emerged. [0003] Most of the mainstream optimization methods are to optimize a large number of detailed structures of the designed schemes, which can easily lead to excessive design with limited effects and lack of integrity; or they are limited in the comparison and selection of schemes in the early stage, ignoring structural design, construction technology, safety guarantee, etc. In terms of optimization spac...
