在金江水库坝体隐患探测中，使用地质雷达发现坝体的主要隐患来自坝体基岩的溶洞和因断裂、裂隙等渗漏通道在残坡积土层中所成的土洞。水库水位浸润线标高和残坡积土与基岩接触界面标高较接近，而使此高程的防渗能力更加薄弱，这也是此坝体的隐患之一。同时，根据地质雷达影像特征可探测灌浆工程的灌浆深度和水泥浆扩散半径，提出它可作为水利部门堤坝灌浆工程质量无损检测的一种新的技术手段。
In the detection of the hidden dangers of the dam in Jinjiang Reservoir, the main hidden danger of the dam body discovered by the geological radar is the cave in the bedrock of the dam body and the soil hole formed in the residual soil layer due to the leakage channel such as fracture and fissure. The elevation of the infiltration line of reservoir water level and the height of residual soil fill and the contact angle of bedrock are close, which make the impermeability of this elevation more weak, which is also one of the hidden dangers of this dam body. At the same time, based on the imaging characteristics of GPR, the grouting depth and grouting diffusion radius of grouting engineering can be detected, and it is proposed that it can be used as a new technique for nondestructive testing of grouting engineering of water conservancy department.
