Zhang Y., Liu Y., Wu R., Zhao J., Tan Y., 2016, Influence of Slot Parameters on the Structure Performance of Slotted Tunnels under the Internal Chemical Explosion, Chemical Engineering Transactions, 55, 1-6.
The chemical explosion is a complicated process with the coupling action of the temperature field and pressure field. Under the internal chemical explosion, tunnels with different slot parameters such as the slot area ratio and the slot depth have different structure performance. In this paper, the influence of slot parameters on the structure performance of slotted tunnels under the internal chemical explosion was studied numerically. 3 schemes were conducted to obtain the structure performance of slotted tunnels, which were different slot area ratios, different slot depths and their different combinations respectively. Based on the finite element analysis software LS-DYNA, the peak vertical acceleration and the peak maximum principal stress of the tunnel roof under different slot parameters were calcutated to obtain the structure performance, which can help provide a reference for the explosion resisting design of slotted tunnels.
