Optimization Of Foundation Support In The Soft Clay Based On The Fuzzy Analytical Hierarchy Process

Building foundations, not only because of its architectural safe and proper use has a very important meaning, and infrastructure projects throughout the building project right budget and schedule heavy is very large, so scientific and rational basis for selecting engineering program is that each project must Essential.Factors to consider building excavation processing soft soil under very complicated and often require them to set excavation, and excavation wide variety of ways, proper excavation mode can be limited space, economy, human etc. the most effective use of resources. At the same time a very wide range of soft clay is present in some areas of the coast, China's coastal areas usually belong to China's economic development arrows areas and soft soil under the building of excessive population density leads to a great demand for this area of the building, so how can efficient conduct excavation of soft soil under the selection has very important significance.This paper introduces the soft soil under the common form of excavation and selection method, then introduced the fuzzy analytic hierarchy process, the technical feasibility, economic viability and environmental factors in the selection of three excavation of the main factors stars three levels, and the use of fuzzy analytic hierarchy process to establish a mathematical model of soft soil under applied by expert analysis at all levels of the weighting parameter determined by law, after a Shanghai project as an example to validate the model in both directions. While in the final optimization of the excavation of the paper chooses to make some recommendations to further improve research.
