Aouthor(s) Yao Li, S.M.ASCE; Yunming Yang; Hai-Sui Yu, M.ASCE; and Gethin Roberts   Abstract Stress–strain responses of Leighton Buzzard sand are investigated under bidirectional shear. The tests are conducted by using the variable direction dynamic cyclic simple...

Structural Analysis for Shallow Tunnels in Soft Soils

Aouthor(s) Minh Ngan Vu; Wout Broere; and Johan W. Bosch   Abstract Generally, studies on structural design for bored tunnels focus on moderate to deep tunnels (cover-to-diameter ratio C/D ≥ 2). Such tunnel design methods cannot be used for shallow-situated bored...
