Stabilizing Loose Soil on a Mountainous Hillside: A Solution to Soil Stability Problems Near Roads
2016 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Soil mass stability problems upon a mountainous hillside are usually discoveredwhen a road is under construction. Therefore a retaining wall need to beprojected. Since this is usually discovered when the production is ongoing, thiscan lead to higher costs. An investigation has been preformed to controlif it is possible to create a standard proposal for retaining walls upon amountainous hillside. Standard proposal can optimize the production of roadsby preventing production stops. Retaining walls near roads which are installedon a mountainous hillside will generate a protection that prevents lose soilmasses from reaching the road. There are four retaining walls that will bedescribed in this thesis, those are: timber walls, concrete retaining walls, pre-made concrete blocks and stacked rock walls. This commission have been incooperation with Norwegian Public Roads Administration NPRA, region north.The software program Plaxis 2D has been utilized to generate a genuine modelthat will represent a real case scenario. Hand calculations have been completedto verify that the model is applicable. If a standard proposal is achievable itmay lower the production costs and secure the unstable slope quicker. Hence,the main reason to manage a standard proposal of retaining walls are tominimize stops within road constructions and faster secure soil masses upon amountainous hillside. With a standard proposal a safer environment and fasterproduction can be achieved.
