Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] Embodiments of the present invention provide a method for simulating water inflow in urban underground spaces, such as figure 1 shown, including the following steps:
[0022] S1. Obtain the basic parameters of the underground space;
[0023] Specifically, the underground space in the city includes underground shopping malls, squares, subways, garages, pedestrian crossings, tunnels, and underpasses for vehicles. , area, area correction rate, drainage pumping station capacity, number of entrances and the width of each entrance, height of water-retaining buildings, ground elevation at the ent...

The invention discloses a simulation method of water inflow of urban underground space. The simulation method comprises the following steps that S1, basic parameters of the underground space are acquired; S2, the topological relation between the underground space and surface elements is established; S3, the water inflow rate of the underground space is calculated; S4, the water accumulation depth of the underground space is calculated. The simulation method is a simple and practicable method for simulating water inflow of the underground space; by combining the method with a surface flood simulation model, whether water inflow happens or not in the urban underground space and the flooding degree after water inflow can be quickly assessed. All basis data required for the method is the most basic feature parameters of the underground space and can be quickly acquired by means of image remote sensing or specification design or field investigation in an area lacking data, and the method is easy to apply in an urban flood risk assessment.
Description
technical field [0001] The invention belongs to the technical field of water supply and drainage, in particular to a method for simulating water inflow in urban underground spaces. Background technique [0002] Since the 1960s and 1970s, London, New York, Tokyo, Paris, Beijing, Shanghai, etc. Big cities have carried out three-dimensional development of urban space, and built a large number of subway lines, underground parking lots, underground shopping malls and underground public facilities. In recent years, affected by the "heat island effect" and "rain island effect" caused by climate warming and large-scale urbanization, urban flood disasters have occurred frequently worldwide due to dam failures, rainstorms and waterlogging. Low "inherently" vulnerable, flooded and severely affected by urban floods. [0003] Underground spaces in cities include underground shopping malls, squares, subways, garages, pedestrian crossings, tunnels, and vehicle overpasses, etc. When subje...
