摘要
随着我国经济不断发展,工程建设及矿业建设中隧/巷道施工越来越普遍,而在施工中不可避免会遇到各种安全事故发生,通过CUGTEM-GK地面瞬变电磁法仪在隧/巷道超前预报实例进行分析,其对巷道掌子面可能出现塌方、滑动的部位、形式、规模及发展趋势及突然涌水、突泥的地点,涌水、地下水泥砂含量等方面具有突出效果,经过实际应用,效果显著,希望此方法可为隧/巷道施工保驾护航。
With the continuous development of China's economy,tunnel/roadway construction is more and more common in engineering construction and mining construction,and various safety accidents will inevitably be encountered in the construction.Through the analysis of the example of CUGTEM-GK surface transient electromagnetic method in tunnel/roadway prediction,it is considered that it has outstanding effect on the prediction of the position,form,scale and development trend of the possible collapse and sliding of the tunnel face,and also has an obvious effect on the prediction of sudden water gushing,mud bursting point,water gushing and underground cement sand content.It is hoped that the practical application of this method can escort the tunnel/roadway construction.
