In this paper, an experimental and numerical study was adopted to investigate the effect geogrid soil reinforcement prestressing on the pressure settlement relation of sand bed supporting a strip foundation. The studied parameters include foundation depth and pre-stress ratio for the cases of one and two pre-stressed reinforcement layers. The study reflected that pre-stressing of soil reinforce...

Footing foundations are sometimes built on sloping grounds of natural sand which is highly anisotropic. The anisotropic mechanical behaviour can significantly influence the bearing capacity a foundation and failure mechanism its supporting slope. Neglecting anisotropy may lead to overestimated under-design foundations. A numerical investigation response slope under strip footing presented, plac...

this paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...

Structured settlement underwriting is the underwriting of medically impaired lives for the purchase of an annuity to fund the settlement. Other than risk assessment, structured settlement (SS) underwriting has little in common with traditional life insurance underwriting. Most noteworthy of these differences is the relative lack of actuarial data on which to base decisions about mortality and t...

In this study, fuzzy logic was implemented to formulate the fuzziness of layer boundaries for a two-layered clay soil. A field of two-layered clay with fuzzy boundaries between layers was generated, and then the bearing capacity of strip footing on this field was calculated by the assumption of plane-strain conditions. The Mohr-Coulomb failure criterion was used and bearing capacity calculation...

Previous comparative analyses of gross and net settlement have focused on the credit risk of the central counterparty in net settlement arrangements, and on the incentives for participants to alter the risk of the portfolio under net settlement. By modeling the trading economy that generates the demand for payment services, we are able to show some largely unexplored advantages of net settlemen...

Existence of these soils, sometimes with high gypsum content, caused difficult problems to the buildings and strategic projects due dissolution leaching by action waterflow through soil mass. In this research, a new technique is adopted investigate performance replacement geosynthetic reinforcement materials improve gypseous behavior experimential set up manufactured loaclally specially for wor...
