Simulation of Slope Failure Induced By Rainfall on Clayey Soils

Landslide is accustomed event in Malaysia and usually occurred during the rainy season
and has taken lots of life and destruct million worth infrastructure. This is a geotechnical failure
induced either by human activity or weather. Rapid development at the hilly area without
supervision of the local authorities and lack of knowledge on soil behavior will leads to the slope
to fails. In other hand, in sub-urban area where there are less development, the slope tend to fails
due to the heavy rainfall. Water pervade into the soil and change the behavior of the soil and
increase the moisture content, pore pressure and mass of the soil. Thus, lead to slope failure.
These research paper aims to study the relationship between rainfall intensity towards the
slope failure by simulate 60% of the exact site condition. Author will simulate the maximum
rainfall intensity, actual slope surface and type of soil from actual site location. Rainfall intensity
data released by Malaysian Meteorological Department will be set as parameter for the study.
Meanwhile, soil sample will be tested to examine the soil properties and its behavior. Moisture
content and pore pressure will be measured as a parameter of the studies. In other hand, author
looking forward for this studies to understand better the factor that leads to this disaster.
