Embodiment
[0041] The invention provides a design method of three consecutive arcs of a tubular culvert, the three consecutive arcs are the top arc, the upper side arc and the lower side arc which are continuous and tangent on the inner contour line of the culvert section. The design of the present invention refers to The calculation of the geometric parameters of the contour line of the culvert section includes the following steps:
[0042] (1) Establish the datum for the design of the inner contour line of the culvert cross-section, and unify it into a reference rectangle inscribed in the inner contour line of the channel cross-section;
[0043] (2) Determine the basic control parameter A and the basic shaping parameter U for the design of the inner contour line of the culvert section. The basic control parameter A for the design of the inner contour line of the culvert cross-section is a known parameter, including the inscribed reference rectangle width B of the inner contour line of t...
