Abstract In the tunneling of the Jinan rail transit line R1 passing under Lashan River，the stability of surrounding rock，the effect of shield thrust and the sensitivity of interface parameters were analyzed employing both the theoretical calculation and numerical method. The study showed that，as the shield passed through the medium interface，the settlement of surrounding rock at arch crown increased firstly and then decreased，while the principal stress in the lining segment increased firstly，then declined and rebounded. The interface effect reached 4 meters to the front and 10 meters in behind. If the safety factor was 2，the support stress ratios maintaining the stability of rock medium，soil medium and excavation face of watercourse were 0.24–2.80，0.34–1.65，0.54–1.40，respectively. The rock-soil interfacial effect was found to increase with the increase of stiffness ratio of medium and interface dipping angle. Especially in the situation of and ，the disturbance sensitivity of interface surrounding rock thrust became more significant.

Key words： tunnelling engineering shield tunnel geological mediums interface effect stability analysis
