测氡技术在铁路采空区勘察中的应用研究
Application Research on Radon Measurement in Detection of Goaf in Railway Engineering
摘要
Abstract
In view of the low survey accuracy in goaf because of perturbation on seismic and electromagnetic survey in areas with complicated topographic condition and interfered by vehicle vibration and transmission line, radon measurement is introduced in railway engineering. Site test shows that there exists an obvious anomaly over a goaf and the anomalies differ in different goaf on account of the radon distributions in the overburden. Methods are established to determine background concentration of radon distribution in the overburden, and standards are put forward to define the anomalies in different goaf. The results show that radon measurement is a useful detection technology in goaf and compensates for some shortcomings resulted from the perturbations on seismic and electromagnetic survey in the areas mentioned above.关键词
