英文摘要	This paper analyzes the tunnel rock ultimate displacement, proposes using acceleration to determine the tunnel surrounding rock stability. Acceleration compared to determine the stability of surrounding rock ultimate displacement method obtained consistent results. Acceleration improved the ultimate displacement method to determine the shortcomings are difficult to quantify. Acceleration of rock deformation by the positive and negative judgments, rock deformation can clearly reflect the trends and status, you can clearly see which one works in a specific state of rock a dangerous warning signal. With a typical project examples validate the method used to determine the displacement acceleration stability of surrounding rock is accurate, feasible. Research and analysis to help build a tunnel surrounding rock stability analysis of the forecasting system. © (2012) Trans Tech Publications.
