Abstract Research purposes: Shield construction is an important method in urban subway construction. Its construction schedule and investment control has very significant complex system characteristics, and is affected by the shield's own factors, construction conditions, construction organization and management, project content, technical standards, financing characteristics and other complex and changeable influencing factors, so there are many problems in the actual control process. In order to optimize the schedule and investment control system, this paper intends to conduct analysis modeling and demonstration.
Research conclusions:(1) Through the processing and analysis of the historical data of the completed project, the construction progress and investment information database of the subway section is established. (2) Nonlinear intelligent methods such as PSO cluster analysis and BPNN can be used to effectively estimate the construction schedule and investment objectives of the shield. (3) The dynamic optimization control management of shield construction schedule and investment can be realized by establishing the model based on PDCA, early warning and other management methods. (4) The dynamic optimization control model is applied in the shield construction of the actual subway section to realize the intelligent and information management of the subway section. (5) The research results can provide a feasible plan for the schedule and investment control of shield construction in the subway section.

Key words： shield construction schedule control investment control PSO cluster analysis BPNN
