Abstract: Abstract In many studies, the face stability evaluations of underground excavations have been performed with an equal-area circular tunnel face instead of the real tunnel shape. This equivalent method greatly facilitates the model construction, but… read more here.

DOI: 10.1038/s41598-020-57632-4
Abstract: Mines and caves provide essential roosting places for bats, but often they are obstructed to prevent entry by humans. To allow bats to access their roosts, metal corrugated culvert pipes are sometimes installed. Wildlife surveys… read more here.

DOI: 10.1080/19648189.2021.1877829
Abstract: Due to the excavation or reinforcement of tunnels, the properties of the rock mass close to tunnels can be significantly changed. To account this issue, a closed-form solution is presented to deter... read more here.

DOI: 10.3390/math12172689
Abstract: The study aims to utilize the convergence–confinement method (CCM) by considering non-hydrostatic stress assumptions in the analysis of the surrounding rock in a circular tunnel. The rock mass properties should adhere to the criteria of… read more here.
