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。
By analyzing the hydrogeological and engineering geological conditions and the spatial and temporal distribution characteristics of ground fissures in the fissure area of Baodi, the ground fissures are considered to be characterized by concentration, repetition and recurrent disasters. The occurrence and development of ground fissures are closely related to the massive exploitation of groundwater in the area. In addition, the direct measurement of radon has been used to measure the ground fissures that have been buried. The “bimodal” measured radon curve provides an effective new method for the detection of ground fissures and the prevention and control of the disasters.
