There are various techniques available to resolve these type issue such as introducing deep foundations, consolidation techniques and soil stabilisation. These methods are time consuming and involves high costs. One effective way of improving such soil condition is introducing granular platform on top of the clay foundation. The load carrying capacity could be further improved by introducing geotextile at the interface of clay/platform layer. Geotextile not only function as reinforcement member, also perform separation, filtration and drainage functions, hence improving the performance of weak clay foundation.
In this research, performance in terms of bearing capacity and settlement will be studied experimentally. Various thickness of platform with prestressing effort will be carried out in three stages. Initially, clay with platform material, secondly geotextile with and without “anchored” position and finally, geotextile in a prestress state will be analysed. Furthermore, Geo PIV (Particle Image Velocimetry) analysis will be used to study particle movement. It is aimed to draw some useful conclusions that can be used in practical design considerations.
