- Abstract:
- Voids behind linings,which are a common form of road tunnel disease,have great danger to the sta-bility of tunnel linings. The previous researches concentrated on plane analysis, researchers considered that lar-ger voids would lead to loop tensile stress at the out edge of the lining which might cause longitudinal crack;However,through establishing three-dimensional finite element model compared with plane analysis,the articleputs forward that voids will leaded to longitudinal tensile stress but loop tensile stress at the out edge of the lin-ing,which possible cause annular cracking. And based on three-dimensional numerical analysis,obtaining theeffect of void behind linings under different surrounding rock and different void locations.
