In step S308, a second spatial bounding box of each second object is acquired.
Wherein obtaining the second spatial bounding box of each second object may include:
for each second object, determining the area occupied by the second object according to the position information of the second object; and expanding the preset range to the periphery by using the area occupied by the second object to obtain a second space bounding box of the second object.
It should be noted that, when the preset range extending to the periphery is 0, the second spatial bounding box of the second object may be a spatial region occupied by the second object, and when the preset range extending to the periphery is not 0, the second spatial bounding box of the second object may be a spatial region extending to the periphery by the region occupied by the second object.

s3091, for each loading point, moving the position of the loading point along the layer height direction to the layer corresponding to the layer height of the loading point.
In the three-dimensional civil engineering structure model, a spatial coordinate system is established, and in the spatial coordinate system, the direction of the layer height generally refers to the direction of the z coordinate axis.
For any load point P1 with a position coordinate of (x 1, y1, z 1), moving the position of the load point P1 along the layer height direction to the layer corresponding to the layer height of the load point may be: the x1 and y1 coordinates of the load point P1 are kept unchanged, and the z1 coordinates of the load point P1 are translated to the layer corresponding to the layer height z2, and the spatial coordinates of the load are P2 (x 1, y1, z 2). For example: as shown in fig. 5, which is a cross-sectional view of the three-dimensional process model in one y-z direction, the loads P1 and P2 belong to 12.495 meters, so that P1 is moved from point a to point A1 and P2 is moved from point B to point B1.

For example: as shown in fig. 6, which is a cross-sectional view in one x-y direction in a three-dimensional process model, assuming that the bounding box is designated as the space footprint of the structural member, both loads P1 and P2 are within the bounding box of the structural member, and P1 is on the centroid axis of the member. Therefore, the P1 position is unchanged, and P2 is translated from the point B to the point B1.
Step S3094, two second objects with the smallest distance from the updated load point are determined according to the positions of the second objects.
The distance between the second object and the updated position of the load point refers to the distance between the load point and the axis of the second object.
S3095, decomposing the load of the corresponding load point on the position of the updated load point to two second objects on the three-dimensional civil engineering structure model.
In the present application, as shown in fig. 6, the load point P3 is decomposed into two loads P31 and P32, and the action points are C1 and C2, respectively.
S3096, according to the distance between the two second objects and the updated positions of the load points, determining the load information decomposed to the two second objects, associating the load information decomposed to the two second objects to the corresponding second objects, and generating the three-dimensional civil structure model with the load information.
The method of moving and decomposing the load may be various, as long as the method conforms to the rule of transferring the load to the structural system, for example: as shown in fig. 6, the load P3 is decomposed into two loads P31 and P32, the action points are C1 and C2, respectively, and the load size of P31 is p31=p3×b/(a+b), and the load size of P32 is p32=p3×a/(a+b), where a and b refer to the distance between the load point P3 and the corresponding second object with the smallest distance, respectively.
When a line load exists, acquiring a starting point and an ending point of the line load, respectively treating the starting point and the ending point of the line load according to a moving and decomposing mode of the point load, and connecting load points decomposed to the same three-dimensional civil engineering member model to serve as a new line load.
