On the Stress-Strain State and Load-Bearing Strength of Argillite-Like Clays and Sandstones

Resumo

The development of the stress-strain state of the soil mass, represented by argillite-like clays and sandstones, at the base of bored end-bearing piles is examined. A method is developed for conducting experimental studies. Stamp tests showing the load-settlement relation were performed and three phases of development of the stress-strain state were identified. Recommendations are formulated for designing bases comprised of argillite-like clays and sandstones.
