Abstract

Landslide is one of the major disasters for damage and loss of life in the world. Every year, this disaster happens. Because of this, many research had been done and method had been introduced in controlling this disaster and reducing the effects. The major factor triggering landslide is the excess of pore water pressure in the soil. The excess of pore water pressure in the slope comes from the groundwater. Controlling the level of groundwater in the soil is vital in order to prevent landslide occurrence. This research aims to control the water level in the soil by the using siphon method and to verify the effects of this system on soil moisture content. This research also analyzes the influence of rainfall on moisture content of soil. Soil's moisture content, bulk density, shear strength and internal angle of internal friction are identified for calculation of factor of safety (FoS). The siphon model was constructed using pvc pipes and two pails. Data collections are divided into several parts. For moisture content, six (6) samples were collected and recorded. From this data, the relationship between rainfall and moisture content of soil is ploted using graphs. The finding shows that the moisture content increases with the presence of rainfall from 0.20 gig to 0.30 gig. The moisture content then slowly decreases to 0.20 at the sixth day. The particle size distribution and shear box analyses, were conducted in the study. The data were recorded by using computer and software of ELE international. The results show that soil with siphon pipe has a cohesion and moisture content of 4.85 k:Pa and 0.3 g/g compared to the soil without siphon pipe which are -4.00 k:Pa and 0.37 gig respectively. As such, siphon system can be applied to control the groundwater level for preventing landslide.
