Pile Scheme Based On Fuzzy Analytic Hierarchy Process Preferred

Infrastructure, high-rise building with a large pile depth and withstand large loads of features, the capacity, stability, security, and so higher requirements, its project cost schedule, quality requirements and the impact on the surrounding environment in the whole project occupies an important position, so I decided to pile foundation design complexity, selection difficult, more needs to be optimized. In recent years, with the extensive application of pile foundation, engineering and technical personnel to ensure the quality of hope, based on the pursuit of higher economic, security and reliability, apparently based on the experience of traditional methods when faced with higher demands explicit powerless. So, follow the safe and practical, economical, and environmental protection principles, establishing a standardized scheme selection process, reasonable and practical scientific research programs preferred method of pile foundation to promote the application has become an urgent requirement.This paper tightly around the pile foundation program preferred theme in the survey and the engineering geological conditions, soil conditions, hydrogeologic conditions, based on the pile foundation proposed several possible solutions. In considering the economic, safety, quality and other factors, and further use of fuzzy analytic hierarchy process to establish evaluation index system, in terms of weight determination combined with single-level sort and index scale to improve and make use of hierarchical sorting method to solve the traditional single AHP consistency test difficult problem. In establishing the index system and fully adopt the opinions of experts, flexible modified to more accurately reflect the views of the experts, reflects the practicality of the method. Requirements for program designers expect fast progress of the project, construction of low cost, high quality requirements, environmental impact assessment and other scientific evaluation, fuzzy judgment matrix, by comparing the program with respect to the major small evaluation right to elect the best pile foundation design.In this paper, a super high-rise project is instantiated verification application are discussed in detail in the pile FAHP program preferred process. Based on the traditional fuzzy AHP on improved, it has more practical rationality, to better meet the requirements of the pile preferred solution, case studies show that the method has a strong practical.
