【摘要】:地質(zhì)雷達探測技術(shù)具有識別度高、對探測目標無損害、試驗操作相對簡便、應用范圍廣泛等優(yōu)點。對復雜地質(zhì)環(huán)境探測,有著非常廣泛的用途,如探測地下采空區(qū)、公路檢測、覆蓋層厚度、滲透水、查找斷層、破碎帶、古溶洞,以及地下埋藏物(如地下管道、電纜、金屬物品等)、人防通道、涵洞等特別有用。 為了研究與分析ZTR12地質(zhì)雷達探測地下空區(qū)的有效性,利用該雷達系統(tǒng)對地下通道、裂隙帶和地下管線分布范圍及深度進行了探測。論文研究的主要內(nèi)容如下: 1.系統(tǒng)分析ZTR12地質(zhì)雷達的技術(shù)參數(shù)選擇以及物理依據(jù),并給出相應的經(jīng)驗值。 2.在不同地質(zhì)環(huán)境條件下,如地下通道、裂隙帶和地下管線,根據(jù)不同區(qū)域電性特征差異性,選擇不同參數(shù)進行探測,并利用地質(zhì)雷達信號處理軟件對試驗數(shù)據(jù)進行分析處理。信號處理方法包括零線設(shè)定、一維濾波處理、背景消除、增益、小波變換等。 3.在不同地質(zhì)環(huán)境,,設(shè)置不同地質(zhì)雷達探測參數(shù),運用不同信號處理方法得到相應的地質(zhì)雷達圖像。試驗結(jié)果表明,對地下通道、淺層滲透水區(qū)及地下金屬管線,ZTR12地質(zhì)雷能探測出空間位置及其埋藏深度;在深層裂隙探測中,由于受ZTR12地質(zhì)雷達有效探測深度的限制,未能取得有效的探測結(jié)果。 4.運用加拿大sensoft EKKO型地質(zhì)雷達在地下通道做對比試驗研究,通過選擇合理的參數(shù),得出較為直觀的探測結(jié)果,與ZTR12地質(zhì)雷達探測結(jié)果相符。 5.試驗表明ZTR12地質(zhì)雷達在淺層地質(zhì)條件下有較好的應用效果,應用試驗研究結(jié)果能夠為今后ZTR12地質(zhì)雷達的使用提供參考。
[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
