地质雷达在玄武岩地区溶洞勘察中的应用

Application of GPR to Detect Basalt Caves in Basalt Areas

玄武岩溶洞是一种特殊的地质现象,其分布范围、空间大小及形状具有一定的随机性,且隐伏于地下,是工程地质中一种常见的不良地质结构,对高速公路工程建设及运营安全构成了潜在威胁。论文以琼北地区某高速公路溶洞探测为例,详细分析了玄武岩溶洞的类型与形成机理,并针对地球物理勘察中地质雷达探测溶洞所获取的典型异常特征及判别标准进行了深入探讨,以期指导玄武岩地区溶洞勘察工作。

Basalt cave is a special kind of negative basalt geology,is a natural geological phenomenon,the distribution,size and shape of the space has a certain randomness,the impact of the project also has a large uncertainty,and buried in the ground,has a potential security threat to the Highway construction and operation.Papers in Northern Hainan Island area of a highway basalt cave detection,for example,detailed analysis of the basalt cave type and formation mechanism,and for basalt cave geophysical survey in the radar of the typical anomalies as well as criterion-depth study to guide the Basalt Regional basalt cave engineering survey work.
