Next, the girder arrangement is arranged in consideration of horizontal alignment, vertical alignment, girder viewpoint level calculation, support level calculation, etc.

First, when the horizontal alignment is completed, the coordinates of each point (abutment, pier) are extracted (plane alignment reference station), the horizontal alignment is offset based on the girder arrangement in the transversal configuration input window, and then the horizontal alignment and each point The intersection point of the alignment perpendicularly offset to the alignment in the part becomes the criterion for arranging the girder.

Then, the point moved based on the linearity of each girder by the separation distance based on the coordinates of each point becomes the girder starting point, and the horizontal linear distance from the end of the slab to the end of the girder is selected.

After selecting the level based on the vertical alignment, the level is calculated by reading the station at the point perpendicular to the horizontal alignment at the coordinates of each point, and then using the superelevation and horizontal distance of the upper slab to calculate the girder viewpoint Calculate the planned height at the top (including superelevation and level distance sections). At this time, the planned altitude at the top of the end point is calculated in the same way to create a 3D Line.

Next, in the calculation of the level at the start point of each girder, the point where it descends vertically to the alignment from the starting point of each girder and intersects becomes the reference alignment station. At this time, the elevation calculation basis map is referred to when calculating the level of the girder in the way that the level of the bearing is calculated in the 2D bridge design.

After that, the reference line separation distance is calculated in the transverse direction from the reference alignment, and if there is a level distance (same level), it is calculated, and the separation distance is calculated by adding the superelevation to the reference alignment design height, and the separation distance is calculated by considering the superelevation It is calculated by adding up in the linear plan, and calculating and summing the pavement thickness and slab thickness to calculate the girder elevation (planned height at the top of the girder).

Next, in the calculation of the support level, the point where it descends vertically to the alignment from the support installation location and intersects becomes the road alignment reference point (Station).

Then, calculate the baseline separation distance in the transverse direction from the baseline alignment, calculate the level distance (same level) if there is one, calculate the separation distance by considering the superelevation and add it up from the baseline alignment plan height, calculate the pavement thickness and slab thickness, Calculate the girder elevation (planned height at the top of the girder) by adding up the girder height and bridge support height (Solplate + bridge support + bridge support block + mortar) to calculate the bridge seat elevation (planned height at the top of the abutment and pier) .
