Analysis And Application Of Investment Estimation Indicators For Highway Bridge Engineering In S Province

With the increasing density of expressway network,bridge engineering,as an important node of expressway construction,its construction cost directly affects the scale of highway investment,and has always been a key management project of the participating units.S province uneven terrain geological conditions,the design of highway Bridges under different geologic conditions are different,so it is necessary for the actual situation of S provincial highway bridge engineering analysis and prediction,building Bridges construction cost index system,so as to better improve the level of the overall design,perfect the highway bridge engineering plan,strengthen the control of engineering cost management.Based on the basic theory of cost management and the literature of its application in practice,this paper analyzes and studies the cost data of high-speed bridge engineering projects in recent years according to the regional characteristics of S province.Precipitation method using information from relevant literature and standardize file selected the 13 highway bridge construction project,then using the expert consultation method,regression analysis on the S the key factor of the provincial highway bridge engineering cost 7(pile foundation,the geological environment,bridge span,bridge across a number of protective structures,pile caps,Bridges,measures the project)and then based on the BP neural network algorithm to complete the design of typical bridge project investment estimation model to create work,finally build S provincial highway bridge engineering cost index system.In a word,the purpose of this study is to provide a set of more effective methods for the investment control of high-speed bridge engineering in S Province.It can provide scientific basis for decision-making of bridge project,reduce investment risk,and improve project cost management level.
