| 摘 要： | 旅游景区栈道由于设计、施工技术资料不详，并经常发生超员现象，存在安全隐患。结合案例工程，根据结点连结方式不同，建立斜柱式栈道力学分析模型。按照实际栈道调查，分别对八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粱上，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。评价认为要保证其结构安全，须确保游人在栈道上单列行走并保持间隔在0．5m以上。但考虑旅游实际需要可增设斜支撑。

| Abstract: | Most of the tilting--column supported aisle which without formal design is overcrowding. Based on the parameters obtained from field survey, there are eight structural patterns summarized. It is found that for a tilt--columned sup- ported aisle structure, the maximum moment and shear forces come into being in the horizontal beam, and the maximum axial force exists in the tilt rod. The maximum internal force models are set up after structure analysis. It is proposed that the structure is safe if the visitors walk separately and intervals a distance of more than 0.5m. But consider the actual needs of tourism, a slope of support can be added. |
