Embodiment Construction

[0017] The present invention will be described in detail below in combination with specific embodiments.

[0018] 1. Carry out block design of the road surface in the area where the transition surface needs to be set, and determine the design elevation value on the sideline where the regular surface and the transition surface meet according to the design slope of the runway, taxiway or contact road. Such as figure 1 , first divide the road panel in the curve area into blocks according to the specified size, and calculate the design elevation value on the sideline of the curve area according to the five corner elevations 12.665, 12.755, 12.555, 12.455, 12.515, and mark it on the road surface These points serve as known points for the design of the curve area.

[0019] 2. The coordinates (x i ,y i ) and elevation values ​​(z i ).

[0020] 3. Suppose it is necessary to calculate the corner coordinates of the new road panel (x 0 ,y 0 ).

[0021] 4. Calculate the horizontal...

Abstract

The invention discloses a method for designing the elevation of the curve area of ​​the road surface. Firstly, the area where the transition surface needs to be set is designed in blocks of the road surface, and the design elevation value on the edge line where the regular surface and the transition surface meet is determined. The elevation value is marked in On the block corner points of the road surface, these points are used as known points for the design of the curve area; the coordinates (xi, yi) and elevation values ​​(zi) of N regular surface edge points are obtained; assuming that the coordinates of the new road panel corner points are (x0, y0); Calculate the horizontal distance from the corner point of the new road panel to each known point, calculate the height z0 of the corner point of the road panel, and mark the height z0 of the corner point of the road panel at the block point (x0, y0) of the road surface , form the block elevation map of the pavement, draw the design contour of the transitional surface area, and check whether the drainage of the design surface is smooth. The beneficial effect of the invention is that the transition of the road surface in the transition zone is smoother, the use of the aircraft is smoother, and the drainage of the road surface is smoother.

Description

technical field [0001] The invention belongs to the technical field of airport runway construction, and relates to a method for designing the elevation design of a curve transition surface of an airport pavement. Background technique [0002] In the design of airport pavement, the vertical and horizontal slope requirements of different parts of the airport pavement are different. Due to different technical indicators, the designed slope values ​​are often different. In the curve area where different pavements are connected, due to the different slopes of the adjacent pavement areas, pavement staggering will occur at the junction. In order to meet the needs of the aircraft, it is necessary to solve the problem of smooth transition of the staggered platform. The current method is to set a new slope at the position of the staggered platform as a transitional surface to make up for the two sides of the staggered platform. However, the new transitional surface is An irregular su...
