Investigation 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 کاملThe effect of nano-Kaolinite on liquefaction resistance of liquefiable sand
This study is an attempt to investigate the effect of the nano-kaolinite concentration on the liquefaction resistance of liquefiable sand from Gorgan city of Iran. To examine the influence of the nano-kaolinite concentration on the liquefaction resistance of nano-kaolinite-sand mixtures, three different nano-kaolinite concentrations: 3%, 6% and 9% were prepared. Cyclic triaxial tests were condu...
متن کاملProcess Modelling and Validation of LNG Re-Liquefaction
During transportation, there will be vaporization of LNG producing boil-off gas (BOG) and its re-liquefaction is required considering that large volume of BOG to be vented out. A cryogenic refrigeration cycle is utilized in order to re-liquefy the BOG and returns it to the cargo tank. Kapitza and claude are the usually used LNG re-liquefaction cycles. The developments in the processes adopted f...
متن کاملThe Relationship Between the Density of Lens and Liquefaction Time Using Liquefaction Device
PURPOSE To investigate the effect of lens density on liquefaction time by using liquefaction device (AquaLase, Alcon Laboratories, TX, U.S.A.). METHODS Cataract surgery using AquaLase was performed on 47 eyes. With a Scheimpflug camera, the density and thickness of lens were measured in eye of each patient preoperatively. During surgery, liquefaction time and total number of pulses were recor...
