FIELD MEASUREMENTS AND ASSESSMENT OF STABILITY OF DAYAOSHAN RAILWAY TUNNEL. LARGE ROCK CAVERNS - PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM, HELSINKI, FINLAND, 25-28 AUGUST 1986. VOLUME 1
Dayaoshan double track tunnel with a length of 14.3 km and highest overburden of 900 m is a key item of the project doubling Jing-Guang Railway (Beijing to Guangzhou), being under construction. The field results of tests and measurement 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 arch with pre-installed multipoint extensometer and deflectometer are discussed. A general assessment of the stability of the tunnel is presented according to measured data and numerical analysis. For the covering abstract of the symposium see IRRD 810647. (Author/TRRL)
