TST超前地质预报技术在贵州岩溶地区的应用
|
摘要
为探索岩溶地区有效的超前预报技术方案,结合岩溶区的地震波场特征,尝试使用基于散射和反射混合模型的TST隧道超前预报技术进行地质超前预报。主要研究成果如下:1)基本查明斗磨隧道进口平导和大独山隧道1#横洞掌子面前方150m预报范围内的地质情况;2)探明隧道掌子面前方岩溶裂隙、溶洞的分布范围、规模以及发育情况;3)预报的结果与实际情况基本一致,为提前采取支护措施提供准确的地质依据。
TST advance geology prediction technology,which is based on the mixed model of scattering and reflecting,is adopted in the construction of tunnels in karst areas in Guizhou.Main study results are as follows: 1) The geological conditions 150m ahead of the face of the parallel adit of the entrance section of Doumo tunnel and ahead of the face of No.1 horizontal adit of Dadushan tunnel are obtained.2) The distribution,scale and development of the karst fissures and karst caves ahead of the tunnel face are predicted.3) The prediction results,which coincide with the actual geological conditions,provide accurate geological basis to take support measures in advance.
