- Abstract:
-
Plank roads in tourist attractions are usually made of local materials, the design and construction technical information are unknown, and crowding often occurs, which has potential safety hazards. The technical route of safety evaluation of plank road is proposed, including four items: the rock mass attached to the plank road, the node of the plank road and the rock mass, the stack structure itself and the auxiliary structure of the plank road. According to the different connection methods of nodes, the mechanical analysis models of cantilever, column and oblique column planks are established. According to the actual plank road investigation, the bending moment, axial force and shear force of the eight models under the corresponding load were compared and analyzed, and it was found that the maximum bending moment and shear force appeared on the horizontal beam and the maximum axial force appeared on the oblique support, and then the most unfavorable internal force verification mode of the plank road was proposed. Combined with the case project, the safety evaluation of the plank road engineering example is carried out, and the applicability of the analysis model is verified.
