USE OF GEOTEXTILES TO BRIDGE THERMOKARSTS THEORETICAL ANALYSIS AND REPORT

This report summarizes the results of a search of available literature and examination of various theoretical methods of analysis to develop a design scheme for using geotextiles as a reinforcement for roadway embankments. The purpose of this reinforcement is to create an embankment able to bridge voids or depressions in the foundation soils caused by melting permafrost. It was concluded that very stiff geotextile fabrics of high tensil strength must be used. The fabric should be placed as close to the bottom of the embankment as possible, and must be strong enough not to rupture under the imposed loadings. The design method proposed includes graphical solutions for the equations developed, and examples of their use. (Author)
