高密度电法与探地雷达在隐伏地质灾害探测中的应用

地下岩溶、土洞及淤泥质洞穴等地质灾害具有较强的隐伏性,对工程施工、地基稳固等会带来不同程度的危害。近年来,关于隐伏地质灾害的勘探,许多学者提出了不同的物探思路与方法。目前,准确探测隐伏地质灾害的规模特征及空间位置是物探工作中亟待解决的关键问题。本文通过采用综合物探的方法,将高密度电法与探地雷达相结合,对地下洞穴塌陷进行勘探,充分发挥两者的优点,资料成果互相验证与补充,排除异常干扰,准确查明了洞穴塌陷的规模特征与具体位置,为工程设计与施工处理提供了科学可靠的指导依据,可在类似隐伏地质灾害探测中推广普及。

Application of High-density Electrical Method and Ground Penetrating Radar to Hidden Geological Disasters Exploration

Geological disasters such as underground karst, soil cave and mud caveare generally hidden, which will bring about different degrees of damage to the engineering construction, foundation stability, etc. In recent years, many scholars have put forward different ideas and methods for the exploration of concealed geological disasters. At present, it is a key problem to be solved urgently to detect the scale feature and spatial location of the hidden underground geological disaster. In , By using integrated geophysical method, high density resistance method and GPR This paper explores the collapse of underground caves, which gives full play to their advantages, and the data validate and complement each other, excluding abnormal interference, and then it accurately finds the cave collapse of the size and the specific location, and provides scientific and reliable guidance for engineering design and construction of treatment. It can be popularized in the similar concealed geological disasters detection
