摘要
本文从分析新奥法的优点及不足出发,系统论述了岩石和围岩蠕变的全过程,从而建立软岩流变地压控制原理,即将围岩中弹性区部分围岩蠕变控制在稳定蠕变范围内,就可以达到既安全又经济的最佳支护状态,并给出了实现这种状态的两条途径。
By analysing the advantages and disadvantages of the New Austrian Tunnelling Method, thispaper sysmatically describes the full creep process of rock and surrounding rock, and the control principle ofsoft rock rheid ground pressure is set up. It means the creeps of partial surrounding rock in its elastic areaare controlled within stable creep range, so the optimal support status with both safty and economy isachieved. The paper also points out two ways for realizing this status.
