Abstract: Due to the presence of cracks the strength of the structure is decreased in the present paper an experimental two dimensional photoelastic technique has been developed to analyze the circular lining tunnel containing cracks. Araldite CT-200 was used to simulate the lining of tunnel and photoflex material was used to model the soil medium.
