Description
Technical Field
The invention discloses a method for measuring and calculating infiltration coefficient of a new urban area, belongs to the technical field of rainfall flood management, and particularly relates to a method for measuring infiltration coefficient of a new urban area by taking low-influence development as a target.
Background
The construction of the new urban area utilizes the measures of 'stagnation' and 'storage' of sponge cities, reduces the runoff of the surface of the earth, relieves the pressure of urban waterlogging, and realizes the runoff control by buffering the change of rainfall. In fact, it is not appropriate for urban new district design to adopt the total annual runoff yield control rate as a planning control standard. A large amount of urban waterlogging phenomena can be seen, the core of urban waterlogging prevention is the design standard of single rainfall, and the runoff formed under the rainfall is only suitable as a planning control standard.
The urban seepage under the condition of single rainfall design standard is an important measurement index of sponge cities.
The infiltration capacity of a new urban area is a parameter reflecting the relationship between rainfall and runoff, and is a dynamic variable which is continuously changed in the rainfall process. The net rainfall minus the infiltration is the runoff. The infiltration amount is influenced by factors such as the type and gradient of the underlying surface, and is also related to the rainfall type, the duration of rainfall and the rainfall intensity, and the solving process is very complex.
Runoff coefficients are generally used in existing urban design for description. The runoff coefficient value is selected mainly by referring to GB50014-2006 outdoor drainage design specification (2016 edition), is a constant value obtained according to a surface type, cannot truly reflect the relation between rainfall and runoff under different conditions, and cannot meet the actual requirements of engineering. There are also scholars (Feng Yuqi, wang Wen sea, lijunqi, etc. Water permeable road runoff coefficient test research, water conservancy and hydropower technology,2019[5]27-35.) measuring runoff coefficient through a test platform, wherein the test device consists of a manual rainfall simulation system, a permeable road and a flow monitoring system, a rainwater collection device is arranged at the tail end, the rainfall process and the road runoff generation have time difference, a certain delay time exists between the measured flow value and the rainfall runoff flow formed by the measured flow value and the rainfall, and only the average value of the runoff coefficient in a certain period of time and the actual value have error [2] 。
Most of the existing invention can only reflect the permeation and accumulation and discharge conditions of a road surface structure, or only can measure a certain road surface structure, and a small number of patents simulate the permeation and accumulation of rainwater conditions (Liu, zhufeng, road industry and the like) of a real road surface structure. There is no suitable comprehensive measurement and calculation method for the complex conditions with multiple underlying surfaces and the multiple terrain features in the new urban area. Accurate estimation values cannot be obtained for infiltration characteristics of new urban areas.
