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...

The liquefaction deformation of sand layer around a bucket foundation is simulated under equivalent dynamic ice-induced loadings. A simplified numerical model is presented by taking the bucket-soil interaction into consideration. The development of vertical and horizontal liquefaction deformations are computed under equivalent dynamic ice-induced loadings. Firstly, the numerical model and resul...

In difficult soil conditions, engineers sometimes choose to combine reinforced soil and spread footings instead of deep foundations. Among the available techniques for soil reinforcement, vibro stone columns are frequently used to reduce the liquefaction risk, improve the soil properties and improve the overall seismic performance. While there are different models available to evaluate the bear...

mas·hyy saturated soil liquefaction during earthquakes, shnakhthshdhyy phenomenon that many researchers in the past three decades has attracted. more research on the liquefaction of saturated soils has focused mas·hyy the natural soils are rarely composed of clean sands, and mixed with clay or silt soils, which is why the study has important ghyrkhmyry and paste. despite numerous studies on the...

This paper investigates the effect of micropile installation into saturated sandy soil by means of finite element method. The obtained results from numerical modeling are compared with the received data from the site. The validation of software has been done by simulating standard penetration test. The effect of some changes in spacing (3m, 1.6m and 0.8m) and injection pressure (1cm, 2.5cm, 5cm...

Computational disaster mitigation and reduction research unit is aimed at developing advanced largescale numerical simulation of natural disasters such as an earthquake, tsunami and heavy rain, for Kobe City and other urban areas in Hyogo Prefecture. Besides for the construction of a sophisticated urban area model and the development of new numerical codes, the unit seeks to be a bridge between...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

Dynamic behavior of soil are evaluated relative to a number of factors including: strain level, density, number of cycles, material type, fine content, geosynthetic inclusion, saturation, and effective stress .This paper investigate the dynamic behavior of saturated reinforced sand under cyclic stress condition. The cyclic triaxial tests are conducted on remolded specimens under various CSR whi...
