Studies show that weak structural faces in jointed rock masses can easily result in large
deformations in tunnels, which significantly affect the safety and stability of supporting …

The jointed surrounding rock is a geological condition that is frequently encountered during
the construction of tunnels. The deformation and strength of jointed rock masses have an …

In present engineering design, rock mass is simply treated as an isotropic material and their
strength parameters are given by decreasing those of intact rock through joint connectivity …

In order to investigate the failure mechanism of multiple parallel tunnels considering the
random distribution of rockmass joints, this paper conducts in-depth study on the instability …

In the past, only displacement, stress, size and distribution of plastic zone can be obtained
when analyzing the stability of jointed rock tunnel. Neither the location and range of the …

After excavation of tunnels in interbedded surrounding rock, accidents such as rock peeling
and arch crown collapse are prone to happen. In response to this issue, we first established …

Based on binocular stereo photography measurement technology, the actual distribution
information of joints and fractures in the tunnel face were obtained via image processing and …

To investigate the instability of two neighborhood tunnels with large crossing section during
the construction, the Tushan subway station was taken as study background, which was built …

During underground excavation many surrounding rock failures have close relationship with
joints. The stability study on tunnel in jointed rock mass is of importance to rock engineering …

Stability of twin tunnels depends on the pillar width and the ground condition. In this study,
large scale model tests were conducted for investigating the influence of the pillar width of …
