Abstract

Recently, as it has greatly increased the demand on the serviceability of subway, cable tunnel, the stability of the tunnel structures has been attracting the concern of engineers and researchers. The purpose of this study is to idently the various characteristics of lining concrete in subway structures. The nondestructive technique such as the surface hardness method and the extend of carbonation by phenolphthalein indicator and chemical analysis due to XRD are considered. Also, the concrete core was cut in three pieces per tunnel for the exact evaluation of strength.
