坑道超前探测技术方法研究及趋势

Research and Development of Advanced Tunnel Detection Technology

坑道掘进过程中,经常遇到不良地质环境的影响,对生产和安全产生严重影响,因而必须实施超前预测与预报。通过对坑道超前探测现状的分析,详细说明了现有技术的使用原理和优缺点,并进行比较。在实际生产中使用什么方法应因地制宜,多种方法相互结合。

In the process of tunnel tunneling,adverse geological environment is often encountered,which has a serious impact on production and safety.Therefore,advanced prediction and forecast must be carried out.Based on the analysis of the status quo of advanced tunnel detection,the application principle,advantages and disadvantages of the existing technology are explained in detail,and the comparison is made.What method to use in actual production should be adapted to local conditions,and many methods should be combined with each other.
