摘要
分析了煤层采空区的变形机理及特征,从支护结构变形、失稳、开裂、涌水、坍方等方面阐述了煤层采空区对隧道工程的危害,并对其危害作了评价,对采空区隧道勘察设计的设计原则、施工工法等进行了探讨,从而提高隧道工程在采空区中的适应性。
The author analyzes the deformation mechanism and the characteristics of the coal gob area, describes the hazard of the coal gob area to the tunnel engineering from the supporting structure deformation, the instability, the cracking, the water gushing and the collapse, evaluates the hazard, discusses the design principle and the construction method of the tunnel survey design in the coal gob area, to improve the adaptability of the tunnel engineering in the coal gob area.
