摘要:

旅游景区栈道通常就地取材,设计、施工技术资料不详,并经常发生人员拥挤现象,存在安全隐患.提出栈道安全评价技术路线,其内容包括栈道依附的岩体、栈道与岩体结点、栈遭结构本身及栈道附属结构等4项;根据结点连结方式不同,建立悬挑式、立柱式、斜柱式栈道力学分析模型.按照实际栈道调查,分别对8种模型在相应荷载下的弯矩、轴力和剪力对比分析,发现最大弯矩和剪力出现在水平横梁上,最大轴力出现在斜支撑上,进而提出栈道最不利内力验算模式.结合案例工程,对栈道工程实例进行安全评价,验证了分析模型的适用性.

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.
