     in recent years, there has been an increasing interest in the tunnel construction. this part describes the squeezing behavior of poor rock mass associated with deformability and strength properties. squeezing phenomena happen in tunnels which are surrounded by weak and moderately strength of rock. squeezing cause to deformed the tunnels cross section and wastes a lot of human and natural source in all of the word every year. the purpose of current study is to determine methods employed to classifying and quantifying of potential squeezing in tunnel. the results show that some part of case-study tunnel has potential of squeezing. along with the empirical and semi-empirical approaches is available in order to evaluating of potential of squeezing in tunnel are presented moreover squeezing potential evaluation of padang renas tunnel which is located in tropical area (malaysia) are presented. . the implications of the anticipated ground conditions and squeezing on machine and ground support selection as well as the field observation of the actual conditions are discussed in this paper.
