Soft clay deposits cause many problems due to low bearing capacity and high deformation. This paper presents the results of laboratory model tests for studying improvement soft clay-bearing using two kinds soil columns, first is slag-cement dust columns second bentonite column. Three from SCC (slag-cement columns) encased by Woven Geotextile are installed beneath a steel plate representing foot...

Ring footings are widely used as a foundation for water tanks, television antennas, silos, chimneys, oil storage etc. This paper is conducted to study the ring footing model's experimental cyclic behavior and circular resting on sandy soil reinforced with geocell. A group of ninety-six test models has been tested investigate shallow footings' beneath loading various rates. Four shapes sand thre...

The study pertains to the investigation of the effect of embedment on the load carrying capacity and settlement of strip foundations on sand reinforced with geogrids. Geogrid being an inextensible reinforcing material is widely used all over the world mainly for retaining walls, abutments slope protection and below the foundation in poor soil. Some research works have been done the investigator...

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 research presents the geotechnical zoning map of district 1 in Shiraz municipality with focus on allowable bearing capacity of foundation based on data from 160 boreholes. For this purpose, the mechanical properties are determined according to the results of direct shear, uniaxial, and SPT tests and then safe bearing capacity for strip foundations with widths of 1, 1.5, 2, and 2.5 m, and f...

Reconstruction and building extensions have become popular trends, even being recognized as one of the most appropriate options for homes, especially in high population density areas or crowded cities. Due to changes size buildings (by applying additional loads), existing foundations themselves are incapable resisting extra stresses. Therefore, it is imperative increase bearing capacity well ov...

Large-diameter open caissons are an increasingly common means of constructing underground storage and attenuation tanks, as well launch reception shafts for tunnel-boring machines. A ‘cutting face’ at the base caisson wall, resembling inclined ring footing, is typically used to aid sinking phase. This paper describes a suite over 15 000 finite-element limit analyses exploring bearing capacity c...
