| Abstract: | Dayaoshan double track tunnel with a length of 14.3 km and a highest overburden of 900m is a key item of the project doubting Jing-Guang Railway (Beijing to Guangzhou), Beijing under construction. The field results of tests and measurements performed near Huashipai inclined shafts 1 and 2 are described. Measurements of initial stress, monitoring of secondary stress, monitoring of convergence and displacements of the tunnel’s side wall and deflectometer are discussed. A general assessment of the stability of tunnel is presented according to measured data and numerical analysis. |
