Research On The Optimization Design Of Soft Soil Foundation Pit In HaiKou Hai-Dian-Dao

With the sustainable development of city construction in HaiKou HAI-DIAN-DAO's region, development and utilization of underground space are gained more attention and there are more and more deep foundation pit projects. So it becomes a realistic need to optimize the design of Deep foundation Pit. Combining with the Project condition and project accident about that region, in the predecessor research results as well as the island experience, this paper including schemes of the supporting system and the detailed calculation and design of the selected program for deep foundation pit, are studied.(1) Using multi-objective optimized project of the retaining system that is of the decision multiple making fuzzy set analysis and attribute and fuzzy property is analytical selected.(2) Based on the engineering data's contrast studies and in the orthogonal design foundation side bad analytic method, the Parameter optimized question of the Cement-soil wall, soil anthor and the Combination plan, are atudied. And the related design proposal are Proposed. Those have certain Project value and the reference significance, for region's deep foundation pit design.(3) Through the selection of decision variables, objective function, constraint condition (i.e. strength, size, displacement etc.) and optimization algorithm, the detailed structure of the selected program can be optimized in order to minimize the cost of construction.(4) Through island in project example analysis and contrast research, Obtained that optimized models in this paper are effective and feasible, have the high reference value and profits from the significance. Those moths Have provided one new efficient path.
