Investigating Stresses Around Tunnels and Piles Using Photo-Elasticity Techniques

---

The method of photo-elasticty was used qualitatively to investiation the behaviour of the effects of pilling on a tunnel. A perspex inclusion was used to resemble the tunnel and stress patterns developed in the granular assembly surrounding it were oveved during the piling process. For a pile installed at a horizontal distance within one ‘tunnel’ diameter of the tunnel axis, bright lines of light were observed joining the base of the pile to the inclusion. These lines of light, respresenting highly loaded chains of particles, developed as the pile as driven in and became most dense at a specific pile toe depth, depending on its position relative to the tunnel. The brightnessof the images also increased as the stress level of the particles increased. At distances further than one tunnel diameter of brightness and number of lines diminished. This observation correclates with centrifuge studies inverstigating the effect of tunnelling on piles (Jacobsz et al.,2003).
