【摘要】 重点阐述地质雷达和岩溶管道裂隙中的水(气)压力传感器自动监测两种监测技术的原理及在岩溶塌陷监测中的应用,对光导纤维监测技术的原理及其在岩溶塌陷监测、预报的应用前景进行了展望。同时分析、说明了三种塌陷监测方法的优缺点和适用条件:地质雷达监测费用昂贵,适用于短距离、小范围监测;光纤监测法适用于各种线状工程监测;岩溶管道裂隙中的水(气)压力传感器自动监测法则适用于由地下水触发的塌陷的监测。更多还原

【Abstract】 <Abstrcat> The paper discusses the principle and application of two kinds of monitoring techniques used in karst collapse monitoring: ground penetrating radar(GPR) and karst groundwater (gas) pressure in conduit. And then,the principle and expectation of the BOTDR used in monitoring and forecasting of karst collapse are also introduced. Finally,advantages and disadvantages of three monitoring techniques were analyzed: the GPR is expensive, thus suitable for short distance, small area and none real-time monitor; the BOTDR is suitable for monitoring linear infrastructure; karst groundwater(gas) pressure monitor techniques is suitable for monitoring the collapse induced by groundwater fluctuation.更多还原
