Experimental research of shell bolting lining mechanical performance in soft rock tunnel

Construction technology of lining concrete in a certain diversion tunnel;

The study on the influence on the behavior of insufficient thickness of roof lining in Baishanzui tunnel structure;

Dynamic stress concentration of SH-waves by arc cracks near a circular lining;

Experimental research on clogging of mat base of inside and outside liner of Yellow River-crossing tunnel by concrete construction

Scattering around a liner of arbitrary shape in saturated soil under dilatational waves

Analyzed the affect of the concrete hydration heat on distribution of temperature and stress field of artificial ice wall while excavating a pit and then pouring mass concrete liner after temperature field of artificial ice is forming.

Study on analytical solution method of circular tunnel lining and surrounding rock stress;

In the light of the drawbacks met in the double-layer lining in soft rock strata,permanent tunnel lining by single-layer reactive powder shotcrete is studied by using numerical simulation and test.

By applying the method of mechanics and combined with the construction situation of railway tunnels,the analysis on the loading situation of the structure of the formworked concrete lining in the single track railway tunnel with the surrounding rock of above Ⅳ class has been put forward,and the comparisons with the actual situation of cracks on the tunnel lining are put forward also in this paper.
