| Abstract: | Based on analyzing the site geological-conditions of a natural gas storage station, a high slope formed by excavating is treated by using spray anchor and framed anchor. Two methods, a limit-equilibrium way from Chongqing local norms and other numerical simulations, are used to analyze and evaluate the treated slope reliability comprehensively. The results show that the slope stability factor, after the implementation of project management, may comply with the requirements of safety norms, and the designed bolts have no damage. The effective treatment of the slope can meet the safety requirements of the natural gas storage station. |
