Bored Tunnel Lining Behaviour in Discontinuous Rock: Railway Tunnel in Middle-East

In a bored railway tunnel project in the Middle-East, difficulties in terms of ovalization, water leakages and settlement of several lining rings located in a fault zone were observed at the end of the construction stage. The present research attempted to find the cause for this lining behaviour. The determination of critical loading conditions,...

Analysis of Single and Group Micropile Behavior: The Bearing Capacity of Single Pile and Pile Groups under Axial Tensile Loading using FEM

This thesis investigates the behavior of single and group micro piles under axial tensile loading. Micro piles are small diameter piles consist of grout and steel rebar and they are capable of absorbing tensile loads. By constructing a group of piles the bearing capacity of each pile within a group is less compared to the single pile. The reason...
