富水地段隧道超前地质预报技术应用

Application of Advanced Geological Forecasting Technology for Tunnel in Water-rich Section

隧道工程是基础设施建设发展的重要组成部分,在复杂的地质条件下,容易发生断层、岩溶等灾害,从而危及工程安全,影响建筑质量。在金迪亚隧道工程施工前的地质超前预测工作中,首先对不良地质段地质状况进行预报和评判,进而提出一种以地质调查为基础,长程和短程预测,多种预测手段相互印证,以地球物理解释为辅助的地质预报手段,形成一套完整的、系统性的,具有时效性的地下工程地质预测工作体系,可以为后续类似的工作提供借鉴和参考。

Tunnel engineering is an important part of infrastructure construction and development.Under complex geological conditions,faults,karst and other disasters are prone to occur,which endangers the safety and quality of the project.In the geological advanced forecasting before the construction of Jindia Tunnel,the geological condition of bad geological sections is forecasted and evaluated.A geological forecasting method based on geological survey,long range and short range forecasting,multiple forecasting methods corroborated and assisted by geophysical interpretation is proposed to form a complete,systematic and time-effective underground engineering geological forecasting system,which can provide reference for subsequent similar work.
