| Abstract: | Combined with projects,it takes Mindlin solution to analyse the influence of shield structure digging going through to the in-use tunnel.It takes semi-empirical formula which is based upon image method theory to analyse the sensitivity of the burying depth of shield tunneling which is caused by soil displacement.Based on flexible foundation beam theory,it calculates the inner structural force of in-sue tunnel caused by the burying depth of shield tunneling. |
