Abstract
Generally speaking, the secondary lining of NATM has been considered the foundation of the cutting surface. Currently, it is presumed only to operate under low Pressure. However, under special conditions such as a squeezing ground, the primary support cannot control rock deformation. Thus, it becomes necessary to have a method to estimate the durability of the secondary lining as a permanent structure.<br>By measuring the squeezing ground and conducting a series of experiments related to rock deformation, we were able to establish a method to estimate the load for the secondary lining. This effective method will play a vital role in the design of secondary lining in the future.
