Abstract

This paper, an evaluation of the mechanical property for the backfilling materials of the NATM Composite lining tunnel using the lightweight foamed mortar, relates to the performance of permeability, compressive strength and unit volume weight. Therefore, this study is aimed to prove the three main factor that refered to the above line for development of new tunnel method. As the result of this study, it would be confirmed that the D mix is better than other mixs a side of all tests and its relation that is for the tunnel backfilling materials.
