CBD-Z14 Business Center Project Pile Raft Foundation Structure Selection And Optimization Design Based On Cost Control

Through the selection and design optimization process of the foundation structure design of a super high-rise twin towers project in Beijing CBD area,the paper particular describes the selection principle and the optimization design method.The selection of foundation types of building structure by the effect of the result which upper load and building structure on the basis,field of engineering geology and hydrological conditions,building function of uneven ground settlement and inclination of sensitive degree and construction conditions and other factors.Above all the factors,the influence of the above structure is the most important factor.Therefore,this paper first discusses the selection process of the upper results,introducted to the basic structure and the structure of the coupling selection process.Then through the description of the main building and podium building area layout selection process,setting up the equation of Optimizing Multi variable optimization.Finally,combined settlement calculation and settlement after pouring belt layout complete basis the overall program to determine the work.Domestic design situation what the design of super high-rise projects involving optimization and selection process,and less involved in optimal design costs,construction demand boast professional contents were optimized from the structure of the single architecture or local area optimization point of view,were less compared with different structure systems and less to between different structure systems fit degree angle selection of design.This paper based on upper and lower different structure system between the degree of fit of,the reference and the use of fuzzy computing philosophy analogy the many Beijing regional development high heat and rare scale projects CBD high-rise buildings foundation scheme,using linear programming method starting from the point of view of cost,construction demand,is construction CBD-Z14 high-rise project based selection and optimization design as an example,introduces the step-by-step optimization under High-rise optimization and selection method.At the same time,how to design links appear subjective factors affecting the cost of the "invalid cost decrease,the relative economic goals that how the foundation slab optimization design technology,economic game relation,by mathematical methods rapid and clear estimates how economic optimum,this paper focuses on the method of.The is in the construction of CBD-Z14 high-rise project based selection and optimization design for example,the analogy of the many Beijing regional development heat higher and rare scale of CBD project high-rise project scheme based economic indicators,using linear programming method from the point of view of cost and construction requirements of the optimal design results made basic comparative evaluation.On the other hand,the basis of the correct selection and optimization of the design level,but also directly reflects the level of design and cost management to the level of forward-looking ideas.So pay attention to the study of building foundation part of selection and optimization of the design work,to improve the overall level of China’s design industry and conducive to real estate development cost control field how to effectively carry out the optimization design ideas clear.The based on the above ideas,borrow encountered in the actual work of the cost and design of cross cutting issues of description for cost-design the total Tongda to relative optimum decision process.
