METHOD FOR DETERMINING OUTLET SPACING IN ROAD DRAINAGE FACILITIES

摘要

PURPOSE: A method for determining outlet spacing in road drainage facilities is provided to determine outlet spacing in road drainage facilities in consideration of a critical rainfall duration time and non-uniform flow analysis method. CONSTITUTION: The reference data for determining the outlet spacing in road drainage facilities are inputted to a surface drainage design program in consideration of a critical rainfall duration time and non-uniform flow analysis method(S210), and the flow used in the road drainage facilities configured by a user is continuously increased. According to the input of the reference data for determining the outlet spacing of the drainage facilities, the surface drainage design program is executed(S220). Through the operation process of the inputted data based on an operation algorithm, the outlet spacing of the drainage facilities is determined(S230).
