[Abstract]:With the rapid development of our economy and the continuous growth of foundation pit engineering projects, the urban construction projects and scale are increasing. At the same time, the engineering technology and problems brought about are becoming more and more extensive and diversified.In recent years, as a key work of safety and cost control of building structure, the optimization of foundation pit support scheme has been paid attention by many engineers and technicians.At present, the optimization form of foundation pit in our country can be divided into three parts, that is, the first part is to optimize the supporting scheme; the second part is to optimize the design details; the third part is to optimize the information management in the construction process.This paper focuses on the analysis of the optimization of foundation pit support.The optimized foundation pit support scheme can obtain the optimum design adaptation engineering from the numerous design optimization, can make the foundation pit achieve better stability, safety and economic rationality.Secondly, the probability of engineering accident can be reduced by optimizing design scheme, and then better social benefits can be achieved while ensuring economic benefits.In addition, by optimizing the design scheme, we can better protect the surrounding environment of the foundation pit, and then create more harmonious environmental benefits.The main contents of the thesis are as follows:First, this paper introduces the recent situation of foundation pit support research, analyzes the research trend and development trend of foundation pit support, introduces various common foundation pit support schemes, and analyzes the importance and necessity of optimization selection of foundation pit support scheme.Secondly, it introduces the basic knowledge of the theory of value engineering, the principle of using value engineering, and summarizes the function evaluation index system with reference to relevant materials.The weight value of each index is determined by Analytic hierarchy process (AHP) and fuzzy evaluation method is adopted to measure the effect of use. On the basis of this the optimal selection model of foundation pit support scheme based on value engineering is obtained.Third, the use of optimal design models for foundation pit support schemes of the Daliang Phase III Hotel Project in Shunde,The implementation process includes: 1, as much as possible to support the completion of the project design, to screen the scheme involved, to compare and analyze the selected scheme, and to optimize and select the model obtained by using the principle of value engineering.The final implementation document is obtained.The optimized selection scheme is put into the structure design. Finally, the quality control objectives of the whole foundation pit supporting structure construction process are analyzed, and suggestions and execution requirements are provided.In this paper, the selection of foundation pit support scheme is summarized and analyzed, and the importance and necessity of optimum selection of foundation pit support scheme are pointed out.Based on the theory of foundation pit support and the theory of value engineering, the function evaluation index evaluation system of optimization selection model for foundation pit support scheme is established, which is of great significance in the selection of foundation pit support scheme in practical engineering.Combined with practical projects, this paper further demonstrates the importance of optimal selection of foundation pit support schemes and the reasonableness of the foundation pit support scheme selection model based on value engineering.Theoretical analysis and practical demonstration show that the optimization of foundation pit support scheme has a great impact on the investment return of real estate projects.
