Mathematical Modelling of the Bearing Capacity of Sibu (Sarawak) Area Peat for Unpaved Road Construction
Peat soils are highly organic soft soils. In engineering terms, they are considered problematic soils due to their high compressibility, high organic content, low shear strength and high moisture contents. These soils constitute a large portion of the land area in the Malaysian state of Sarawak and in its Sibu region in particular. Construction on such soils is often difficult and unpredictable. It is desired to implement a prediction strategy whereby engineers can foresee the shear strength of such soils for future unpaved road construction considerations. As such, a research program was devised to use 3 mathematical models to predict the strength of local Sibu area peats. The models used are: Love et al. (Can Geotech J 24:611–622, 1987, [15]), Barenberg (Design procedures for soil-fabric-aggregate systems with Mirafi 500X fabric, Civil Engineering Studies, Department of Civil Engineering, University of Illinois, Illinois, USA, 1980, [2]) and Giroud and Han (J Geotech Geoenviron Eng 130:787–797, 2004, [5]). For comparison with the theoretical models, peat was sampled from Sibu, from the area near Tun Zaidi Stadium. Results show that Barenberg (Design procedures for soil-fabric-aggregate systems with Mirafi 500X fabric, Civil Engineering Studies, Department of Civil Engineering, University of Illinois, Illinois, USA, 1980, [2]) and Giroud and Han (J Geotech Geoenviron Eng 130:787–797, 2004, [5]) models provided the lowest bearing capacity results in comparison to Love et al. (Can Geotech J 24:611–622, 1987, [15]). Therefore the former two can be considered for any conservative bearing capacity design involving local Sibu (Sarawak) area peaty soils. Generally, these local peaty soils can be used as subgrades for unpaved roads, taking into consideration the local conditions of the study.
