Settlement Analysis of Road and Storage Areas Based on Organic Soil Surcharged by Ash – Slag Layer

Abstract

The outlet distance of large river, Odra in Poland is a place where large area of the terrain is made of peat. Those places are close to the river so the investors would like to use the area for industrial purpose having direct access to the waterways (cheap transport). One of the methods to reinforce the soft soil (peat) is consolidation. In the presented case the surcharging layer is made of fly ashes. The researches have been done at the Technical University of Szczecin that allow to formulate a mathematical description of peat consolidation in case when elasticity modulus of peat increases along with the consolidation process and the permeability coefficient for peat decreases. The method also allows to calculate the terminal settlement of the peat layer in a long time. The method was invented by Z. Meyer. The paper presents the method and the results of practical calculations in the case of peat from area of Szczecin – Skolwin close to Odra River in Poland.
