Comparative study of the tunnelling work for different ground condition / Mohd Sanusi Mohd Yusoff

Tunnels are structure, which are recognised as one of the alternative to accomplish convenient transportation routes through she conditions posing natural difficulty or special hazards. There are different ground conditions, which are commonly encountered in tunnelling work. The selection of excavation / tunnelling procedures and techniques very much depend upon the types of ground condition. This study is to make a comparison of the various geotechnical problems encountered in tunneling work for different ground condition in Malaysia. The study will be done for two different types of ground condition. One of the case study is PUTRA - LRT System Two Tunnel Sections at Kg. Baru Project in Kuala Lumpur, which is tunnelling through soft ground. The second case study is the Genting Sempah Second Tunnel Project at KL - Karak Highway, which the tunnel was excavated through a hard rock. The comparative study highlighted the geotechnical problems encountered where tunnelling through hard and soft ground with and the respective problem solving methods.
