Lightweight, high energy reservation and excellent functional performance are the main
benefits of cellular concrete. Its properties mainly depends on the pore characteristics …

The use of yielding supports has proven to be a highly effective measure for tunneling in
squeezing grounds because of their agreement with the law of mechanical movement of …

Abstract Traversing the Qinghai–Tibetan Plateau, the Sichuan–Tibet Railway is by far the
most difficult railway project in the world. The Qinghai–Tibetan Plateau features the most …

Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it
reduces dead loads on the structure and foundation, contributes to energy conservation, and …

The roadway support has always been a difficult problem in the mining engineering,
especially in the deep soft rock roadway, whether it can provide endurable and effective …

The roof of coal seams are mostly soft rock with weak cementation. To further study the
mechanical characteristics and deformation control scheme of the roadway with weakly …

The application of compressible layers is considered to be the most promising solution for
solving the problem of large deformations in deep soft-rock tunnels. However, although …

Deep soft rock roadways generally present large deformation characteristics, and a vast
number of workers attempt to repair them to no avail. A true 3D model test was performed …

Deep-buried tunnels constructed through layered soft rocks undergo large deformation,
which threatens their safety and leads to construction delay. When a soft rock tunnel is …

As an energy-absorbing material, foam concrete has gained recent application in tunnel
support systems. Despite its capacity for substantial compressive deformation, including …
