Design Designers The Validation of Parameters for Rainwater Storage System in Beijing Olympic Common Domain Underground Park Abstract in this article, through the rainfall simulation experiments in both simplified unit and the standard unit, validate the reasonableness and accuracy of the flood control standard for Beijing Olympic common domain underground park. When a 50-year return period rainfall happens, ensured the roads, squares and other major facilities are not dropsied; when a 100-year return period rainfall occurs, guaranteed the flood did not enter the entrances and exits of commercial buildings underground; at the same time, validate the standard of usage of rainwater meets the design standard, when encountered a 50-year return period rainfall, surface runoff did not produce, all rainwater infiltrated and collected.
