Tourism Infrastructure Structural Safety Evaluation Of Technical Research

In recent years, with increaseing of social wealth and improving of people's living standards, China's Tourism is rapiding development. However, due to the unsound rules and regulations, poor experience of managers, lacked of safety awareness of tourists and laged of research in tourist safety, accidents are frequently occurrence in tourism.Researching on the tourism safety is still at preliminary stage.There is very few studies in domestic tourism security in China. Previous studies always stoped at the operational level and an in-depth theoretical analysis and interdisciplinary research is very few.Neither these studies researched from the Tourism infrastructure themselves nor many Tourism infrastructure in the region are builded whitout original design data. Because of those,the safety of Tourism infrastructure can be repute as a most vulnerable link in case of accidents in tour.So that is very important to evaluation of structural safety in Tourist District.This paper extract the main structure (including Truss-supported Aisle(TSA), spiral staircase, suspension, etc.)based on a tourist facilities in Henan Province and advance the structural safety evaluation of different methods, but also propose preventive measures base on collapse,landslide ,debris flow and other environmental problems.Give major conclusions as follows:a. It is proposed that the procedure of TSA safety assessment be divided into four steps: the assessment of supporting rock, evaluation of joint between rock and TSA, calculation on TSA and checking on the appendix structure of TSA.b. The main form of TSA is tilt-columned. It is found that for a TSA 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.c. The seismic action effects may be less than the effect of wind load, wind load effects may be the main link to security control in high-rise structure such as spiral staircase. d. In order to evaluate the spiral staircase's safety,we should be checking it's greatest pressure, tension and overall stability in the most unfavorable combination.It could be enhancing the link at the end of the foot, increasing the depth of mounted to reinforced the high-rise facilities which risk in aecurity.e. Taking into account the long-span suspension bridge in Tourist District are usually smaller, and the main live load is visitors, Static calculation is recommended in suspension bridge in Tourist District.Because of the smaller load,it could be sufficiently accurate results in small and medium-sized suspension bridge with Static calculation.
