【摘要】 本文介绍一种新型的隧道施工综合超前地质预报系统USEP,该系统采用综合参数法进行超前地质预报,综合参数为"波速+电阻率"。其中波速探测采用角度偏移和位置偏移的联合体系,电阻率探测采用瞬变脉冲电磁法重叠回线装置在掌子面进行扫描,最终实现综合参数及空间超前地质预报。文章利用课题组研发的USEP系统,结合108国道北京南村隧道的探测预报实例详细说明隧道综合参数及空间超前地质预报工作的原理与效果,并总结在复杂地质条件下采用"波速+电阻率"综合预报的必要性,它对隧道及地下工程施工超前地质预报工作有广泛的指导作用。更多还原

【Abstract】 This text introduce a new tunnel comprehensive geological prediction system of USEP,it uses Synthetical parameter method to predict geological features ahead of construction face.Synthetical parameter is wave velocity and resistivity.Wave velocity detection uses combined system of angle offset and position offset,and resistivity detection uses overlapping circle line of TEM to scan at the tunnel face,Synthetical parameter and space geological prediction can be achieved at final.The research team developed a USEP system which was applied to construction of the NANCUN tunnel on the No.108 national highway to show work principle and effect of tunnel Synthetical parameter and space geological prediction,and the necessity of tunnel comprehensive geological prediction using wave velocity and resistivity under complicated geological condition was summarized.It has extensive guide role on advanced geological prediction of tunnel and underground engineering construction.更多还原
