In mining excavation, the roof bending subsidence of gob-side entry driving heading
adjacent to the advancing working face (HAWF) can be considerable. Influenced by the …

Rocks are natural geo-materials, whose properties are affected by many spatially-varying
factors, such as the properties of their parent materials, weathering processes, and …

Considering shortcomings of the current technology in controlling ground surface settlement
and reducing the effect of excavation on the surrounding environment. This paper presents …

Recent developments in tunneling have stimulated design practitioners to more effectively
utilize the underground spaces. However, tunneling at shallow depth in soft grounds gives …

With advances in numerical modeling techniques, the combined finite-discrete-element-
method (FDEM) is increasingly being used to study the mechanical behavior and failure …

Due to the influence of sedimentary environment, the coal seams and overlying rocks in the
wind oxidation zone exhibit developed fractures, high rock porosity, strength attenuation …

This paper presents a case study of closely spaced triple tunnels with large sections in
Beijing, China. The mechanical responses of three cross-sections were systematically …

Our goal was to develop an effective research tool for tunnels with significant deformations
supported by arch–bolt union system. The improved numerical simulation approach is …

To address the inadequacies of traditional pipe-roof methods, the steel support cutting pipe
