Simulation and Evaluation of Sponge City Reconstruction Effect in Urban Drainage Residential Area by YU Haijun, FAN Yuyan, CAO Daling, CHEN Wei

“…Drainage effect evaluation is a necessary links in the construction of Sponge City,and urban rainfall mathematical models are important supporting tools for the evaluation work.Taking a residential area in Beijing City as an example,a refined drainage model of the study area was constructed based on a coupled 1D and 2D hydrodynamic model for urban rainstorms,and the drainage situation before and after the sponge transformation of the drainage system were simulated and analyzed.The results showed that the constructed model can well reflect the real drainage situation of the community,and the proposed drainage system upgrade plan can effectively improve the drainage capacity in the area,and the overflow and submergence were significantly reduced.The research can provide some technical reference for the simulation of the hydraulic condition of drainage community and the construction and management of Sponge City.…”

Research of the Transfer Method of Four-dimensional Coordinate to Three-dimensional Coordinate by Ran Xiaoyan, Zhang Bai

“…The coordinate measure machine（CMM） with rotary table is often use in the field of precision measurement.Because of the error evaluation requires that all measured point must be expressed in the same coordinate system,but the workpiece coordinate system is changed in the process of measuring because of rotation of rotary table,so it is difficult to evaluate errors.Therefore,a model for coordinate transfer from four-dimensional coordinate system to three- dimensional coordinate system is created.Through the transfer algorithm of coordinate system,the four- dimensional coordinate with rotary table can be transferred to a three dimension Cartesian coordinate by utilizing rotary table coordinate system to act as medial coordinate system,then,it can be transferred to workpiece coordinate system or machine coordinate system,sequentially,the error evaluation is realized.The experimental results show that the mathematical model is right,and it can meet the requirement of precise measurement.…”
