A METHOD FOR THE STABILITY ESTIMATION OF THE WALL ROCKS OF MID OR SMALL—SCALE TUNNELS

本文介绍了评价中小型隧洞(道)围岩稳定性的经验公式,并应用于一工程实例。结果表明,该方法适用于地质条件较好,试验工作较少的中小型隧洞围岩稳定性的评价。

This paper presents a method used to estimate the stability of the wall rocks of middle or small-scale tunnels.This method has been applied to a engineering case.The result indicates that the method is suitable for the stability estimation of middle or small-scale tunnels where geological conditions are relatively good with little test work needed.
