The Optimization Solution And Optimization Design For The Deep Excavation Support Project

The Deep Excavation Project is a complicated system project. How to acquire asafe and reliable, economical and reasonable, technically feasible and easilyconstructible support structure solution becomes a problem in the DeepExcavation Project Design. Due to the large amounts of influencing factors on theexcavation support and the reaction among all factors, looking for an effective way tosolve such complicated problem turns into a hot potato in the industry of geotechnicalengineering; the dissertation starts from how to solve the problem of a optimizationdesign for the Deep Excavation Support Project, combines with the practical example ofthe project, analyzes the application of Analytic Hierarchy Process into the practicalproject, and proves about the selected results through the application of the deepexcavation software.The main research contents of the dissertation include:First of all, the dissertation analyzes the features and developing situation of thedeep excavation project, combines features of different support types of excavations,systematically formulates the basic theory, counting method and designing principle ofthe support structure design of the deep excavation, and analyzes and introduces to thecommon support structure design.Second, the dissertation demonstrates the necessity and feasibility of theoptimization of the deep excavation, and analyzes and discusses about the selectingtheory.Third, the dissertation constructs an evaluation index system of the optimizationfor the support structure design of the deep excavation, confirms the importance of eachindex by the application of the Analytic Hierarchy Process, so as to build up thecomprehensive evaluation model on the evaluation support solution. On the basis, thedissertation puts forward a preferably systematic optimization model of the deepevaluation support solution. Combining the practical project, the dissertation makes afurther discussion on the application of the Analytic Hierarchy Process into the practicalproject.Fourth, the dissertation uses the Matlab math software to write the optimizationprogram of the deep excavation support, and the Lizheng deep excavation designingsoftware to optimize the design of the excavation, so as to make the results morereasonable and more reliable, as well as cut down the cots.
