Deep Foundations for the Bangkok MRT Chaloem Ratchamongkhon Line Metro Project
Richard E. Prust, Peter A. Thompson
The Bangkok Mass Rapid Transit (MRT) Chaloem Ratchamongkhon Line project is the first underground subway to be completed in Thailand. It consists of 33 km (14 miles) of twin-bored tunnels and 18 cut and cover stations constructed within the deltaic deposits that underlie the city. This paper describes the ground conditions, site investigation, including the use of the self-boring pressuremeter and the associated design issues for the construction of deep foundations. The paper also describes a selection of the various deep foundation solutions that were adopted to address particular constraints of the project and the ground conditions, including slurry walls for the cut and cover stations and foundations used for the underpinning of existing structures.
