Assessing slope failure of soil erodibility problem by soil dispersive identification

Abstract

Dispersive soils are becoming a common building material. Due to their susceptibility to internal erosion and leakage, dispersive soils should only be used in combination with precise engineering measures to avoid catastrophic failures. Dispersive soils stabilization is critical and has been investigated in several studies conducted throughout the world. Erosion is a significant issue in structures built on sloping contours. As was the case with St. 670+250 Lipat Kajang road in Aceh Singkil. Soil erosion happens as a result of water’s dispersion and transport force. Dispersive soil is one of the factors that contribute to an increase in the soil erodibility index. The objective of this research is to develop a method for enhancing the soil’s dispersive qualities. In this investigation, specimens were prepared in three different soil mix plans (10%, 20%, and 30%) and then tested using a pinhole. The quantity of erodibility that happens in Sta. 670 + 250 Lipat Kajang - Aceh Singkil Regency is based on the results of testing the soil's dispersive properties because the soil in this area is highly dispersive.

The potential of NAA and ICP-MS for determining soil dispersibility in relation to landslide incidents

“…While it is commonly believed that the occurrence of dispersive soil is limited to region with arid or semi-arid climates, other countries globally have encountered challenges associated with this phenomenon [2,3]. Dispersive soil has been reported in various tropical nations, including Thailand, Vietnam, Indonesia, and Malaysia [4,5,6,7]. Several regions of Malaysia, prior studies have documented the presence of this particular type of soil in Batu Gajah, Wangsa Maju, Shah Alam and East Sabah.…”
