Studies On Health Evaluation Of Foundation Pit Engineeirng Based On Fuzzy Comprehensive Evaluation Method

In this article, proceed from the characteristics and the actual application of f-oundation pit engineering, in the analysis of all kinds of diseases of foundation p-it engineering and their causes, determine the main influence factors of integratedhealth of foundation pit engineering in four main areas: Leakage water of founda-tion pit, surrounding environment conditions of foundation pit, deformation of reta-ining structure of foundation pit, pit’s internal environment. And proceeding fromthe four main areas, established the11comprehensive health assessment index offoundation pit with regard to these four areas, composed evaluation index systemof comprehensive health evaluation system of foundation pit engineering. By dra-wing on relevant industry experience of Health assessment of construction work, c-ombined with practice, integrated many considerations, building evaluation collecti-on of comprehensive health assessment of Foundation pit engineering, thereby un-derstanding the operational status of foundation pit. Evaluation index system andevaluation collection of foundation Health comprise a comprehensive health asses-sment of foundation pit engineering.In comprehensive health assessment system of Foundation pit, with AHP theo-ry, established a structural system of foundation pit health assessment. By fuzzycomprehensive evaluation method, research and experience of the health evaluationof reference-related industry engineering, determine weight of comprehensive healt-h assessment index of foundation pit engineering, and established the comprehensi-ve health evaluation model of foundation pit on fuzzy comprehensive evaluationmethod. Combining engineering instance, selected " station Hall deep foundation pi-t engineering of Tianjin station rebuilding project " as a case, by comprehensivehealth evaluation model of foundation pit engineering based on fuzzy comprehensi-ve evaluation method, assess the comprehensive health of foundation pit. For suchtemporary service engineering of foundation pit engineering comprehensive healthassessment of the preliminary inquiry.
