Experimental investigation on the mechanical properties of tunnel lining with the blocked longitudinal drainage pipe under rainfall conditions
To investigated the impact of rainfall conditions and longitudinal drain blockage on the lining structure safety of karst tunnels
the Hu-Xi-Tai Tunnel of Zhejiang Lin-Jian Expressway was used as a supporting engineering
the mechanical properties of the tunnel lining structure under different water head heights and longitudinal drain blockage degrees were investigated adopted by indoor physical model experimental methods
and the field monitoring analysis was carried out in different rainfall seasons. The results illustrate that: (1) The decline rate of the water level in the karst cavity increases almost linearly with the increase of water head height. However
when the water head exceeds 50cm
the increase rate slows down
indicating that the drainage capacity of the tunnel is insufficient. (2) The drainage volume continuously increases with the increase of water head height
and the increase rate gradually accelerates
particularly after reaching a water head of 80cm. (3) The water pressure behind the lining and the pressure stress of the lining structure both continuously increase with the increase of the water head height. Moreover
the growth rate significantly accelerates after surpassing a water head height of 50cm
with increases of 77.2% and 39% respectively. (4) The greater the degree of drainage pipe blockage
the more sensitive the change of water pressure behind lining and pressure stress of lining structure with the water head height. Compared to low blockage conditions of longitudinal pipe
the water pressure and pressure stress growth rates increase by 27.6% and 60.9% respectively when the longitudinal pipe is completely blocked. These research results can provide a theoretical basis for the safety assessment of lining structures of karst tunnels under heavy rainfall conditions.
