FRICTION PILES FOR A WALKWAY ON A PEAT BOG

This paper describes work carried out to investigate the suitability of using timber friction piles placed in peat to support a raised walkway across Clara bog in the midlands of Ireland. First, trial piles were used to examine the feasibility of the method and to investigate the bearing resistance and settlement of friction piles in peat. Groups of four piles were used to support rectangular timber platforms carrying test loads. The ground conditions, such as the water content and the undrained shear strength of the peat, are discussed first. The trial pile test results are then discussed. The results show that: a) the piles can be driven by hand (conventional pile driving equipment can damage the weak peat); b) the piles can support load without excessive settlement; c) the amount of settlement is related to the stress ratio. For the covering abstract of the conference see IRRD 863640.
