Abstract. The bearing behaviour of large-diameter monopile foundations for offshore wind turbines under lateral cyclic loads in cohesionless soil is an issue ongoing research. In practice, mostly the p–y approach applied design monopiles. Recently, modifications original monotonic loading stated API regulations have been proposed to account special piles with small length-to-diameter ratios. Ho...

Dissociation of methane hydrates in the Arctic permafrost may lead to explosive gas emission. Methane blowout be triggered by increasing flow rate at a certain depth. The mechanism rock failure and under effect pressurized was studied numerically laboratory experiments. problem formulated for unsteady compressed depending on given depth, pore pressure variations were calculated as function dept...

Soils are called problematic soils when they do not have sufficient bearing strength to provide a founda-tion for the structures be built on them and these types of need improved with appropriate methods depending their properties. Improvement applied strengthen often cause financial burden. Recently, there studies about use waste rubber tires, which pose an environ-mental risk during storage, ...

This paper presents an improved earth pressure method that considers the capacity of a wall toe to carry load predict connection loads GRS segmental walls constructed with cohesionless backfills on competent foundations. In this method, response surface model (RSM) lateral coefficient replaces Coulomb active coefficient. The parameters RSM were determined from numerical studies impacts restrain...
