为适应我国隧道建设机械化、智能化、无人化发展趋势,围绕钻爆法机械化施工隧道,提出以凿岩台车破岩振动为震源的钻爆法机械化施工隧道随钻地震波超前地质探测技术.针对凿岩台车多震源连续激发带来的地震数据波场混叠、有效信息难以识别问题开展相关研究,提出VMD-SVD-RobustICA三臂混合先导信号分离方法与脉冲反褶积-小波域互相关地震记录重构方法,可实现三臂混合先导信号的分离与有效反射信号的提取.工程实践证明,利用凿岩台车搭载式无线高精度探测装备,该技术可初步实现"边钻边探",降低预报环节对钻爆法机械化施工隧道正常施工带来的影响.最后,明确该技术目前存在的问题及解决思路.
To adapt to the trend of mechanization,intelligence,and unmanned development of tunnel construction in China,around the mechanized construction tunnel of drilling and blasting method,the authors propose an advance geological detection technology of seismic waves while drilling via the drilling and blasting method in mechanized tunnel construction.The drilling and blasting method takes the rock-breaking vibration of a drilling jumbo as the source.Further,the authors propose solutions regarding the problems of wave field aliasing and identification of effective information of seismic data caused by the multi-source continuous excitation of the drilling jumbo.Subsequently,the VMD-SVD-RobustICA three-arm mixed pilot signal separation method and the pulse deconvolution-wavelet domain cross-correlation seismic record reconstruction method are proposed.The separation of three-arm mixed pilot signals and extraction of effective reflection signals are realized.Using the wireless high-precision detection equipment equipped with the drilling jumbo,"exploring while drilling"is preliminarily realized,and the influence of the advance geological prediction on the mechanized tunnel construction by the drilling and blasting method is reduced.Finally,the existing problems and solutions of the proposed technology are discussed.
