摘　　要：通过对宝坻地裂缝区的水文地质与工程地质条件及地裂缝的时空分布特征分析，认为地裂缝具有集中出现、反复活动、重复致灾的特点，其发生发展与当地大量开采地下水活动密切相关。此外，应用直接测氡法对已经掩埋的地裂缝进行测量试验。＂双峰型＂测氡曲线为地裂缝的探测及其灾害的防治提供了一种有效的新方法。he Authors, through the analysis of the hydrogeological and engineering geologicalconditions of the Baodi geofracture area, and the space-time distribution featuro of geofracture,consider that the geofracture has the chara cteristics of centralizedly occuring, repeatedly moving,and repeatedly resulting in disaster; and its occureuce and development have sth. to do with theoverpumping of groundwater in this area. In this paper, the authors carry out the tests to theburied geofracture by applying Radon method, get the curve of bimodal Radon distribution; andoffer a new effective method on the detection, the prevention and cure of geofracture.
