| Summary: | Most of the past researchers have conducted investigations on the dynamic loading of soft soils such as sand and clay
but there are still lacks of information on discovering the behaviour of peat in terms of static and dynamic loadings. Hence,
this paper presents the dynamic behaviour of Western Johore peat pertaining to four different effective stresses which are
13kPa, 25kPa, 50kPa and 100kPa by using 1Hz loading frequency. The main objectives of this study is to establish the
shear modulus and damping characteristics of Parit Nipah peat and Pontian peat located in West Johore, Malaysia. The
Index Properties test, Monotonic Triaxial test and Cyclic Triaxial Test have been performed to determine the parameters
required by using one way loading and stress-controlled method. All tests were conducted in the laboratory in Research
Centre of Soft Soil, Universiti Tun Hussein Onn Malaysia. The analysis describes that the variation of shear modulus
increase as the effective stresses increases from 200kPa to 1200kPa for PNpt and from 100kPa to 1150kPa for POpt.
Meanwhile, the damping ratio shows a reduction when effective stresses increases from 0.25 to 0.03 for Parit Nipah peat.
Besides, damping ratio of Pontian peat reduce from 0.30 to 0.05. For a better comprehension of the subject, further
investigations on dynamic loading of peat soil required to critically identify the consequences on dynamic parameters |
