Impact of Micropiles Installation on Liquefaction Potential of Saturated Silty Sand Using Numerical Method
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...
متن کاملInvestigation of Liquefaction Mechanism and Displacement in Buried Sand Layers
One of the most important reasons for damages during earthquakes is the liquefaction of loose and saturated sand soils. However, in many regions with proper soil specifications, the large settlements have been observed in the ground surface. Loose sand layers buried in fine soils are one of the cases which may result in these problems and as a weak point during earthquake can cause this phenome...
متن کاملInvestigation of Liquefaction Mechanism in Double Sand Lenses
In many cases of heavy earthquakes, liquefaction has resulted in serious damages. Existing anisotropy in soil layers results in some difficulties to realize the reason for these phenomena. Loose sand lenses buried in fine soils are one of the cases which may result in these problems and as a weak point during the earthquake can cause this phenomenon. In this paper, using FLAC 2D software, doub...
متن کاملPassive Site Remediation for Mitigation of Liquefaction Risk (2000-2001)
Passive site remediation is a new concept proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction. It is based on the concept of slow injection of stabilizing materials at the edge of a site and delivery of the stabilizer to the target location using the natural groundwater flow. Stabilizer candidates need to have long controllable gel times an...
متن کاملThe Effects of Grain Size Distribution and Structure on Mechanical Behavior of Silty Sand
In order to investigate the effects of the grain size distribution and the micro-structure of soils on the mechanical characteristics, some static triaxial compression tests were carried out, and then the relationship of stress-strain and the strength behavior of silty sand were compared among undisturbed samples with different grain size distribution, undisturbed and remolded samples with the ...
