Abstract

In recent years, geologist and soil scientist have increasingly sought out organic soil, including peat in tropical regions to study their characteristics and agricultural potential for new development area. However, few studies had been made to analyse the consequences of cyclic loading onto peat. The aim of this study is to determine and analyse the behaviour of dynamic parameters on different locations of peat using cyclic triaxial test. Sample preparations and testing methods on analysing the dynamic parameters are briefly explained. Results on Index Properties test and Cyclic Triaxial test are presented for all peat locations. It has been concluded that the behaviour of damping ratio, D and dynamic shear modulus, G in PNpt, POpt and SBpt are influenced by the basic physical and chemical properties like moisture content, organic content and fibre content which affected by its site condition and environmental growth. The percentage of fibres and its sizes that contained in each peat samples also could be the major causes pertaining to the Malaysia’s peat dynamic parameters behaviour.
