SELECTING PILE CONSTRUCTION METHOD USING FUZZY APPROACH

摘要

The selection of pile foundation construction method depends mainly upon the subjective opinion of construction practitioners. Therefore, this experience has to be documented and stored in the intelligent company database for usage in future pile construction projects. This research introduces an attempt to store the experts' subjective experience using a fuzzy expert system (FES) or fuzzy model. The proposed model uses soil type, environmental conditions, water table position, and granular strata location as input variables. It produces the appropriate pile construction method and its associated membership value as outputs. The FES system is designated based upon construction facts and practitioners opinion. It is validated and a sensitivity analysis is performed to check its sensitivity to any changes in the inputs. It proves its robustness in selecting the appropriate pile construction method.
