The Water Saturated Peat Mechanics Properties Research with Taking into Account Excessive Pore Pressures

摘要

The article describes the excessive pore pressures influence (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. Although, authors made the new experimental device for research of the water saturated peat mechanics properties with excessive pore pressure.
