  摘要: 隧道工程中存在許多難以預(yù)計的不良工程地質(zhì)現(xiàn)象,其嚴(yán)重影響隧道的正常施工.在對區(qū)域地質(zhì)和掌子面巖性勘查的基礎(chǔ)上,通過對廈蓉線黔東淺變質(zhì)巖區(qū)的探地雷達(dá)圖像解譯分析,探討了裂隙帶、斷層破碎帶及富水帶的雷達(dá)圖像特征,以此說明建立“以地質(zhì)法為基礎(chǔ),探地雷達(dá)為主要物探手段”的綜合超前地質(zhì)預(yù)報體系的重要性,為該區(qū)雷達(dá)測試提供圖像信息庫.

  Abstract: There are some unfavorable geological phenomena,which have a strong bad impact on tunnel construction. The advanced geological forecasts for epimetamorphic rock were perfected in tunnels of Qiandong zone at Xiarong Line. The images of GPR were analyzed on the basis of geological condition of region and lithology of tunnel face. The features were discussed,include geologic radar features images of rock integrity, fault fracture zone, enriched ground water zone and fissure zone. So it is important during the advanced geological forecast to build a complex method,a basis of geology and a main geophysical method of GPR. And for a certain area, all images enrich the geological information of GPR.
