Abstract

The paper reports the excess pore pressures effect (that arises in shrinkable peat foundation) on its own physical mechanical characteristics. The authors suggested the upgraded assembly scheme of the soil pressure sensors (load cells). The laboratory research of the water-saturated macro peat sample was made in compression conditions with “ground lock” and modeling of the experiment with Plaxis 2D software system. The unit deformation-pressure graph and excessive pore pressure against time in different steps of load graph were built and based on this findings.

Summary

Introduction

The West-Siberia is the world leader in marshes concentration and marshes formation. Waterlogged soils cover more than 50% of a whole territory e.g. [1]: Russian Federation area is 17098.2 thousand square kilometers.West Siberian area is 2454.1 thousand square kilometers. The paper reports the excess pore pressures effect (that arises in shrinkable peat foundation) on its own physical mechanical characteristics. The laboratory research of the watersaturated macro peat sample was made in compression conditions with “ground lock” and modeling of the experiment with Plaxis 2D software system.
