It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...

Abstract This paper aims to study the behaviour of a circular footing resting on two granular layers, i.e., dense sand layer loose strata, subjected vertical and an inclined loading (?=0°, 10°, 20°, 30°) using finite element (FE) software PLAXIS-3D. The Mohr-Coulomb criterion is employed for analysis model, in which parameters are considered vary significantly; (1) thickness top (dense layer) (...

The artificial freezing method can effectively improve the stability of strata and provide favorable conditions for construction safety shield tunnel in water-rich strata. Based on frozen tunneling project a metro station, which is close to important buildings, reasonable parameters are proposed this paper. simulation model was established by using Plaxis 3D finite element software (Version 201...

the pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. in most situations, we have to transfer these granular soils from the borrow area, usually far from the site of the project. this will impose a considera...
