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 کاملDevelopments in Liquefaction Analysis from Observations during Earthquakes
Liquefaction has occurred during most earthquakes, Niigata 1964, Tangshan 1976, Loma Prieta 1985, Kobe 1995, Chi-Chi Taiwan 1999, Turkey 1999, Haiti 2010, Mexicali 2010 and others. The performance of structures during the Niigata earthquake (1964) in Japan and the nature of damage suffered by them clearly brought out the fact that soil and soil foundation interaction play a significant role in ...
متن کاملVertical ground motion and its effects on liquefaction resistance of fully saturated sand deposits
Soil liquefaction has been extensively investigated over the years with the aim to understand its fundamental mechanism and successfully remediate it. Despite the multi-directional nature of earthquakes, the vertical seismic component is largely neglected, as it is traditionally considered to be of much lower amplitude than the components in the horizontal plane. The 2010-2011 Canterbury earthq...
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 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...
