Effect of Construction Cessation on Tunnel Stability in Completely Weathered Granite Stratum
Abstract: Cessation, taking place often in tunnel construction due to various reasons, usually cause tunnel collapse in weak ground if the cessation time is long. Dongkeling tunnel on GuizhouGuangxi line being as the engineering background, the 3D viscoelasto-plastic rheological model was established to find the evolving rules of deformation at critical locations such as the tunnel crown, arch springing...

Experimental Investigation on Rheological Properties in Completely Weathered Granite
Abstract: Completely weathered granite(CWG) exibits very poor water stability, distinct rheological properties and noticable regional difference. In order to grasp the rheological properties in CWG along Guizhou to Guangxi railway, the Dongkeling tunnel on the railway taken as the background, test samples were taken on the site and processed into three groups with different water...
