Investigation on interaction between soil strength and plant
Abstract
Landslides are the major natural hazard in mountainous countries. The failure of slope is usually triggered by precipitation. Slope stability is dependent on the shear strength of the soil. Plants influence the stability of slopes in a number of ways and can be used to increase the slope stability. The plant canopy may cushion the impact of raindrops and reduce surface erosion. Plants draw water from ground through their roots and evaporate by their leaves. The evapotranspiration reduces the water content in soil and increases the soil strength against potential slope failures. Moreover, plant roots reinforce soils, resist erosion, and increase the infiltration of water into the soil. Some of these factors are difficult to quantify. This project aims at quantifying the effect of plants on the shear strength of soil. The problem will be investigated by experiments and numerical simulations.
