A COUNTERMEASURE TO FROST HEAVE OF MULTI-ANCHORED RETAINING WALL IN COLD REGION

Abstract

2-D computer simulations for the longterm field experiments were carried out to determine a possible range of ground freezing around a multi-anchored retaining wall. Temperature fields were calculated on several shapes and sizes of walls. Simplification was made for heat transfer calculation on material constants of soil, such as thermal conductivity, heat capacity. The depth and shape of freezing front was determined the required range for soil replacement to protect walls against frost heaving.
