Application of BP Algorithm in Cost Estimation of Water Conservancy Project

In recent years, with the rapid development of my country’s economy and the deepening of reform and opening up, the development of water-saving projects has increased rapidly, and the investment entities of water-saving projects have shown a trend of diversification evolved into various changes. My country’s engineering cost management started late, and it has not received enough attention from WCPs. The establishment of the theoretical knowledge system is not perfect, and some traditional cost methods are gradually being abolished. In this paper, I aim to study the application of BP algorithm in water conservancy project (WCP) cost estimation. This paper analyzes the basic idea of BP algorithm, the principle of WCP cost estimation model and the function of project cost estimation. It also analyzes the WCP evaluation model based on BP algorithm and the determination of the WCP index system, and draws the experimental results. The empirical analysis results show that after adopting the BP algorithm, the performance of the traditional WCP cost estimation method has been greatly improved, and we conducted a questionnaire and found that more than 79% of the people felt that the design WCP cost estimation method was applied to the BP algorithm. It is found that the design efficiency has become high.
