Description
Summary:The mechanical stabilisation of soil slopes by means of tree roots depends largely on the strength properties of the roots and their growth pattern within the soil. In particular areas, the selection of indigenous tree species on the basis of their root properties is an essential part of biotechnical slope protection. In order to determine the effects of tree roots on slope stabilisation in the mountainous area of Khao Luang, southern Thailand, seven tree species were studied. The distribution and penetration of the roots was established and their tensile strength and pull-out resistance determined. The paper evaluates the potential contribution of each of these species to slope stabilisation with reference to existing slope conditions.
