【摘要】:地质雷达探测技术具有识别度高、对探测目标无损害、试验操作相对简便、应用范围广泛等优点。对复杂地质环境探测,有着非常广泛的用途,如探测地下采空区、公路检测、覆盖层厚度、渗透水、查找断层、破碎带、古溶洞,以及地下埋藏物(如地下管道、电缆、金属物品等)、人防通道、涵洞等特别有用。 为了研究与分析ZTR12地质雷达探测地下空区的有效性,利用该雷达系统对地下通道、裂隙带和地下管线分布范围及深度进行了探测。论文研究的主要内容如下: 1.系统分析ZTR12地质雷达的技术参数选择以及物理依据,并给出相应的经验值。 2.在不同地质环境条件下,如地下通道、裂隙带和地下管线,根据不同区域电性特征差异性,选择不同参数进行探测,并利用地质雷达信号处理软件对试验数据进行分析处理。信号处理方法包括零线设定、一维滤波处理、背景消除、增益、小波变换等。 3.在不同地质环境,,设置不同地质雷达探测参数,运用不同信号处理方法得到相应的地质雷达图像。试验结果表明,对地下通道、浅层渗透水区及地下金属管线,ZTR12地质雷能探测出空间位置及其埋藏深度;在深层裂隙探测中,由于受ZTR12地质雷达有效探测深度的限制,未能取得有效的探测结果。 4.运用加拿大sensoft EKKO型地质雷达在地下通道做对比试验研究,通过选择合理的参数,得出较为直观的探测结果,与ZTR12地质雷达探测结果相符。 5.试验表明ZTR12地质雷达在浅层地质条件下有较好的应用效果,应用试验研究结果能够为今后ZTR12地质雷达的使用提供参考。
[Abstract]:The geological radar detection technology has the advantages of high recognition degree, no damage to the detection target, relatively simple test operation, wide application range and so on. For the detection of complex geological environment, it has a very wide range of applications, such as detection of underground goaf, highway detection, overburden thickness, seepage water, fault search, broken zone, ancient caverns, as well as underground buried objects (such as underground pipelines, cables, metal objects, etc.), civil air defense channels, culverts and so on. In order to study and analyze the effectiveness of ZTR12 geological radar in detecting underground empty area, the distribution range and depth of underground channel, fracture zone and underground pipeline are detected by using this radar system. The main contents of this paper are as follows: 1. The technical parameter selection and physical basis of ZTR12 geological radar are systematically analyzed, and the corresponding empirical values are given. two銆
