“…As mentioned previously, many of the tall buildings, including the Q1 tower are located in the centre of the study area within these two cross sections. Moreover, physical and engineering properties of the peat layer have been obtained from the soil investigation reports of the Surfers Paradise area Table 2. the literature (Huat 2004;Duraisamy et al 2007;Huat et al 2009) and showed that the peat in Surfers Paradise falls within the range of the tropical peat.

The subsoil conditions of Surfers Paradise in Southeast Queensland of Australia have been examined in terms of soil stiffness by using geographic information system (GIS). Peat is a highly organic and compressible material. Surfers Paradise (as a study area) has problematic peat layer due to its high water content, high compressibility, and low shear strength. This layer has various thicknesses at different locations ranging between R.L. . 10 to R.L. -19.6 m. Buildings in Surfers Paradise are using piled foundations to avoid the high compressibility and low shear strength peat layer. Spatial Analyst extension in the GIS ArcMap10 has been utilised to develop zonation maps for different depths in the study area. Each depth has been interpolated as a surface to create Standard Penetration Test SPT-N value GIS-based zonation maps for each depth. In addition, 8 interpolation techniques have been examined to evaluate which technique gives better representation for the Standard Penetration Test (SPT) data. Inverse Distance weighing (IDW) method in Spatial Analyst extension gives better representation for the utilised data with certain parameters. Two different cross sections have been performed in the core of the study area to determine the extent and the depth of the peat layer underneath already erected buildings. Physical and engineering properties of the Surfers Paradise peat have been obtained and showed that this peat falls within the category of tropical peat.

“…In this research, the tube sampler taken from the site was carefully extruded and cautiously trimmed to a diameter of 50mm and a height of 100mm using a sharp knife and was quickly weighted to minimize the disturbance on the moisture content [14]. For triaxial testing, the specimen was enclosed in a high-density latex membrane and porous stones and filter papers were inserted at the ends of the specimen.…”

Abstract. Peat soils are challenging soils which are a problem for many geotechnical engineers especially in the design of shallow foundations and road constructions. The engineering properties of peat are dependent on the nature of its physical properties. Micro structural studies done on the soil shows that it consists of fibres which cause the soil to be highly compressible resulting in excessive settlement when they are subjected to moderate load increments or vibrations produce by traffic. In this paper, dynamic testing was done to approximately simulate traffic loading characteristics on peat taken from Parit Nipah and Pontian, Johor using a cyclic triaxial testing with 1Hz loading frequency. The results were compared with soil that has a stiffer particulate nature such as sand. The comparison showed that the dynamic loading parameters of dynamic shear modulus and damping ratio of peat was dependent on the fiber content and was very much lower than that of well graded and uniform sands. This can be an important indication to understand the key parameter behaviour of peat that must be taken into account when designing and managing infrastructures on peat soils.

“…The binder is carried in pressurized tanks, which are mounted on the rig itself or on a separate shuttle. A research has been carried out in University Putra Malaysia (UPM) to examine the effect of cement column on the compressibility of peat soil [7] . When a cement column is installed in peat, its compressibility is reduced because of the hardened skeleton matrix formed by cement particles bonding with adjacent soil particles in the presence of pore water.…”

“…The results indicated that compressibility index Cc and Cα decreased with increasing diameter of the cement column. Specimens with 45 mm and 60 mm diameter of cement columns were cured for 28 days, after which they were subjected to Rowe Cell Consolidation test [7] . Undisturbed samples of peat soil were taken from three different locations in Banting (located on the West coast of Peninsular Malaysia) by using a sampling tube.…”

This paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and long term (creep) settlement. With the ever increase in the cost of living and the decrease in suitable land for construction, avoidance of marginal tropical peat soil is never going to be the popular choice among the developers and town planners. This paper gives some insights on the construction methods that could be possibly employed to develop marginal ground such as tropical peat soil.
