Sponge City Reconstruction Design Optimization of Industrial Plant Based on SWMM-An Example of Tianjin Cigarette Factory Technical Transformation Project Phase Ⅲ
Taking the third phase of Tianjin Cigarette Factory technical transformation project as the research object,artificial water injection tests were carried out on the common green space,common concave green space and carbon fiber module green space in the project site,and the model parameters such as porosity,water production capacity,exhaustion point and permeability coefficient of soil layer under different structural conditions were determined according to the test data.Through the simulation and analysis of SWMM model of urban storm water management,the influence of the common concave green space and the carbon fiber module concave green space on storm water runoff under different rainfall intensity and rainfall duration was studied with the control sample of the green space runoff before the project renovation.The simulation results show that the water production capacity and permeability coefficient of the sunken green space equipped with carbon fiber modules are improved,and the control ability of stormwater runoff is stronger.The optimized sponge city benefits are relatively better,which can provide reference for other similar renovation projects.
