摘要
文章结合常德市某小区地下车库底板渗漏水的工程实际,采用LTD-2600型地质雷达配备400 MHz屏蔽天线对地下车库地板进行扫描探测,确定了在该设备及工程适用场景下地质雷达对水体反射信号的频谱区间;对比分析了有无渗漏水病害区域雷达探测结果的剖面图像特征,在雷达图像分析的基础上对雷达信号进行频谱特征进行分析,进一步分析与判别了地下车库渗漏水区域下方富水区域的现状。
In combination with the engineering practice of the water leakage of underground garage floor in a residential community in Changde City,this paper uses LTD-2600 ground penetrating radar equipped with 400 MHz shielding antenna to scan and detect the underground garage floor,and determines the spectral range of the reflected signal of the ground penetrating radar to the water body under the applicable scene of the equipment and the project.The section image characteristics of radar detection results in the area with or without water leakage disease are compared and analyzed.Based on the analysis of radar image,the spectrum characteristics of radar signals are analyzed,and the current situation of water-rich area below the leakage area of the underground garage is further analyzed and discriminated.
