1. A method for cable laying by stress analysis, comprising:
detecting a cabling channel and determining horizontal positions and heights of discrete points in the cabling channel by a total station for pipeline detection;
segmenting the cabling channel into a plurality of segmentations according to a segmentation information attribute comprised in each discrete point, wherein each of the segmentations comprises successive discrete points, and the segmentation information attribute comprises cable grounding manners, cabling manners and cable bending types and the step of segmenting comprises: initially sorting and numbering the discrete points from one end of the cabling channel to the other end of the cabling channel according to a direction of the pipeline detection; obtaining first level segments by performing first level segmentation on the discrete points according to the cable grounding manners; obtaining second level segments by performing second level segmentation on discrete points in each first level segment according to the cabling manners; and obtaining third level segments by performing third level segmentation on discrete points in each second level segment according to the cable bending types; wherein after each of the first level segmentation, the second level segmentation or the third level segmentation, the method further comprises: re-sorting and numbering discrete points within each segment of the first level segments, the second level segments, and the third level segments according to a cabling direction; and
performing stress analysis calculation on each of the third level segments according to segmentation information and measurement information of the discrete points, wherein the segmentation information comprises the cable grounding manners, the cabling manners and the cable bending types that correspond to segments in which the discrete points are located, the measurement information comprises coordinates of the discrete points, a friction coefficient for laying cables and a weight of each cable per unit length, and the stress analysis calculation comprises at least one of calculation of a traction force or calculation of a side pressure;
laying the cables in the cabling channel according to a stress analysis result thereby protecting the cables, wherein the stress analysis result comprises at least one of the traction force or the side pressure, and the at least one of the traction force or the side pressure is applied to each segment of the cable in real time during laying process to prevent excessive local stress on the cable.
