A review: Soil structure interaction of railway structure in Malaysia permanent way

The upgrading of the Northern-Southern Railway Line to accommodate for future High Speed Rail (HSR) soon to be constructed. The nature of soil between places are varied thus create a problems for railway engineers to lay down Prestressed Concrete Sleeper (PCS). Soil-structure interaction is very important to ensure any structure stand and distribute the load to ground. A lot of cases has been reported due to low soil-structure interaction. The sign of a low soil structure interaction can be seen in short or longer period of time. PCS were located directly above ground and if the soil-structure interaction is low, the result will be catastrophic. There have been reported that certain rail track line were located at a problematic soil (settlement) and the rail engineer have to monitor the situation on regular basis. Hence, this research aims to understand more about the relationship between the PCS and soil thus creating awareness to relevant authorities to tackle this problem.
