The tunnel is one of the most important components in modern underground engineering. Due to long and narrow shape constraints, it very easily results large-scale fire explosion when deflagration caused by accidents vehicles that transport dangerous goods tunnel. Previously, studies on damage lining high-temperature impacts these kinds disasters were often limited a discussion only influencing factor, either or explosion, but they rarely considered two factors simultaneously. In this work,...
This paper presents studies that focus on fire and explosion‐induced damage of tunnel structures by employing the Discrete Element Method (DEM). By assuming a two‐dimensional aggregate distribution reconstructing digital representation experimental concrete blocks, numerical model lining was established in PFC 2D program. The temperature shock wave pressure at surface were obtained using Fluent LS‐Dyna separately; final simulation section under different conditions carried out . results...
A new method for increasing the interface resistance between geopolymer coating and concrete lining structure without applying organic binder was suggested in this study. Parallel grooves with different depths orientations were milled on top surface of block, well-blended mixture (Na-PSS type geopolymer: Sodium poly-sialate-siloxo) coated upon grooved interface. The wedge splitting (WS) experiments conducted to compare adhesion capacity specimens groove width/depth ratios orientations....
