Abstract


Deep foundation pit supporting structure design is very important step is to determine the type of supporting structure . Theoretical development and engineering practice to promote the development of deep foundation pit support programs , but the selection method to use more traditional methods of artificial , scientific and high degree of intelligence . Five common deep foundation pit support structure type , the paper focuses on the deep foundation pit supporting structure selection decisions based on BP neural network . Papers as the starting point to the deep foundation pit support engineering theory and a lot of deep foundation pit support engineering examples , the identification of deep foundation pit supporting structure selection decisions affect the formation of deep foundation pit supporting structure selection decision factors index system ; introduces BP neural network theory , the salient features of the deep foundation pit support structure selection involves many fuzzy uncertainties in the MATLAB language environment , the preparation of the decision-making process of selection and build the deep foundation supporting structure selection decision-making model ; formed by a large number of project examples of learning samples Knowledge Base training and commissioning, network selection decision model of deep foundation pit support structure . Finally the selection decision-making model in practical engineering , design , multi-level fuzzy comprehensive evaluation method and project monitoring data point from experts to verify its practicality and effectiveness . The selection decision-making model is convenient to use , more effective solution to the deep foundation pit support structure of the preferred issues .
