Research On The Road Engineering Cost Prediction Of Taihu High-speed Railway Area Based On BP Neural Network

In recent years,China’s municipal infrastructure has been constantly improved,the length of municipal road construction has increased rapidly,and the drainage pipe network facilities have become increasingly complete.Governments at all levels continue to strengthen the construction of municipal infrastructure,and the investment in municipal road drainage construction is gradually increasing.It is of practical significance to accurately predict the cost of municipal road drainage engineering in the early decision-making stage of the project.However,the municipal road drainage engineering cost prediction model has certain deficiency.This dissertation mainly studies the municipal road drainage engineering cost prediction model,combines with the actual project data of Taihu county to train the model,and further seeks a new method to predict the municipal road drainage engineering cost of Taihu county.First of all,this dissertation expounds the research background,purpose and significance of the municipal road engineering cost prediction,and sorts out the research status of the project cost prediction at home and abroad.Secondly,the theoretical knowledge related to municipal engineering,municipal engineering cost and BP neural network is introduced in detail,which lays the foundation for the subsequent construction of BP neural network cost prediction model.Then it describes in detail the general situation,development status and problems of Taihu high-speed railway area road engineering project.Finally,the paper introduces the principle of BP neural network algorithm and the main factors affecting the municipal road project cost,establishes the municipal road project cost prediction index system,constructs the BP neural network model of municipal road project cost prediction,and uses the collected municipal road project sample data of Taihu county for training and testing.And the model is used to predict the cost of Taihu high-speed railway area road engineering project.According to the prediction results,the prediction accuracy of the cost prediction model can meet the requirements,which provides a fast and feasible method for the local municipal road engineering cost prediction in the future,and also provides a reference for the municipal road engineering cost prediction method in China.It has certain practical significance.
