【摘要】:地質(zhì)雷達(dá)探測技術(shù)具有識(shí)別度高、對探測目標(biāo)無損害、試驗(yàn)操作相對簡便、應(yīng)用范圍廣泛等優(yōu)點(diǎn)。對復(fù)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(dá)探測地下空區(qū)的有效性,利用該雷達(dá)系統(tǒng)對地下通道、裂隙帶和地下管線分布范圍及深度進(jìn)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(dá)的技術(shù)參數(shù)選擇以及物理依據(jù),并給出相應(yīng)的經(jīng)驗(yàn)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(jìn)行探測,并利用地質(zhì)雷達(dá)信號(hào)處理軟件對試驗(yàn)數(shù)據(jù)進(jìn)行分析處理。信號(hào)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(dá)探測參數(shù),運(yùn)用不同信號(hào)處理方法得到相應(yīng)的地質(zhì)雷達(dá)圖像。試驗(yàn)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(dá)有效探測深度的限制,未能取得有效的探測結(jié)果。 4.運(yùn)用加拿大sensoft EKKO型地質(zhì)雷達(dá)在地下通道做對比試驗(yàn)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(dá)探測結(jié)果相符。 5.試驗(yàn)表明ZTR12地質(zhì)雷達(dá)在淺層地質(zhì)條件下有較好的應(yīng)用效果,應(yīng)用試驗(yàn)研究結(jié)果能夠?yàn)榻窈骦TR12地質(zhì)雷達(dá)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
