【Abstract】 n order to produce a reliable survey method for the study prediction as well as prevention and control of ground fissure, the possibility of radon anomaly is, firstly, analyzed in ground fissure started with the basic principle of surveying radon and the genetic mechanism of ground fissure. Secondly, it is clearly confirmed that the radon anomaly is sure according to the surveying profile. Then the characteristics of radon anomaly and its geological background are emphatically discussed by analysing the profile curve of radon in ground fissure. Finally, it is proposed the judgement of radon anomaly in ground fissure.更多还原
