Effects of Vegetation and Soil Type on the Stability of the Marankiari Road Slope, Chanchamayo

Abstract

The research article presents the results of a study aimed at understanding the effect of vegetation and soil type on the stability of road slopes in the province of Chanchamayo. The data and methods section includes tables showing in detail the analyses carried out in the Soil Mechanics laboratory for slope stability purposes, as well as graphs showing the safety factors and percentage increase in the safety factor considering vegetation independently to see their effects on each type of soil. In the results it was observed that both vegetation and soil type have a significant influence, profile 3 is already considered unstable in the analysis due to the type of soil alone, but if we apply vegetation such as Tillandsias in pseudostatic conditions the safety factor in relation to the initial value of soils increases by 16.36% while in static conditions the safety factor does not increase significantly since it is the most critical profile unlike profile 1 in which in static and pseudostatic conditions with Albizia carbonaria vegetation the percentage increases by 8.35% and 11.14%; and in profile 2 with Ochroma vegetation pyramidale in static and pseudostatic conditions the percentage increase was 16.39% and 19.23%.
