摘要:
通过开展真实火灾实验和数值模拟研究,考察隧道内温度变化情况,对比分析不同高度的分布式感温光纤对温升或温差的响应规律,进一步研究光纤敷设间隔与隧道高度的关系。结果表明,光纤敷设的最大间隔应随着隧道高度的增加而逐渐减小。最后,对照国内各地方标准及其他国家的标准规定,得到不同敷设高度感温光纤对应的最优光纤敷设间距。该研究结果对分布式光纤火灾探测系统的实际应用有一定指导作用。
Abstract:
Through real fire experiment and numerical simulation research, the variation of temperature field in tunnel was investigated, and the response regularity of distributed temperature sensitive optical fiber with different height to temperature rise or temperature difference was analyzed. Furthermore, the relationship between the laying spacing of optical fiber and tunnel height was studied, and the results showed that the largest laying spacing should be decreased gradually with the increase of tunnel height. Finally, the optimal laying spacing correspond to different laying heights of temperature sensitive optical fiber were obtained by comparing the domestic local standards and national standards. The results have a certain guidance for the practical application of optical fiber fire detection system.
