Subsea structures are typically supported on mud mat type foundation systems. Traditional approaches for mud mat foundation stability analysis consider calculating the factors of safety using the classical methods given in API RP 2A or the more recent API RP 2GEO. Due to the inherent uncertainties in soil properties and subsea structure forces, conservative factors are generally required, conse...

Shallow Soil Mixing (SSM) is a sister technology to Deep Soil Mixing (DSM) developed to more economically improve soils within ten meters of the surface. SSM was recently utilized to provide a foundation for large effluent storage tanks as well as to contain foundation soils in the event of liquefaction from an earthquake. Two large storage tanks were required to be built in a pulp mill. The on...

Abstract One of the most critical engineering problems that occur in foundations machines resting on soil is problem transmission vibration from machine to foundation and then soil. This leads increased stresses layers settlement as well. In this article, an experimental model a rotary located gypseous sandy (36% gypsum content) has been studied. The weight with was 26 kPa subjected 10 Hz frequ...
