Liquefaction is a disaster that can damage building infrastructure. This all too common in granular sandy soils. due to the subsidence and instability of soil when subjected shocks such as earthquakes. For this reason, mitigation efforts are needed reduce risk liquefaction. study will compare effectiveness influence micro-pile, stone column, densification methods on soils at Central Java PLTU s...

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 ...

The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

Liquefaction triggering assessments are often performed for individual locations, providing little information in regard to the expected spatial extent of liquefaction events. The present paper proposes a method to quantify the potential extent of liquefaction by accounting for spatial dependence of soil properties and potential future earthquake shaking. Random-field theory and geostatistics t...

This paper presents prediction of liquefaction potential of soils by neuro-fuzzy models evaluated using Idriss and Boulanger method. In order to address the collective knowledge built up in conventional liquefaction method, an alternative Takagi-Sugeno-Kang reliant neuro-fuzzy model has been developed. Neuro-fuzzy is one of the artificial intelligence approaches that can be classified by machin...

Earthquake induced liquefaction in saturated granular soils is an important phenomenon causing severe damages. In order to minimize the ill-effects due to liquefaction, various lab tests, field tests are being used which assess the liquefaction potential. In the present study the shake table test has been used for assessing soil liquefaction of loose saturated cohesionless sand by simulating ea...

Abstract Monolayers (MLs) of transition‐metal dichalcogenides host efficient single‐photon emitters (SPEs) usually associated to the presence nanoscale mechanical deformations or strain. Large‐scale spatial control strain would enhance scalability such SPEs and allow for their incorporation into photonic structures. Here, formation regular arrays strained hydrogen‐filled one‐layer‐thick micro‐d...

during the last years the total cost of lng technology has decreased significantly due to improvements of the liquefaction process. however, many liquefaction plants that are still in operation use a three-cascade refrigeration system. in this paper, an advanced exergetic analysis is applied to better understand the operation of a three-cascade refrigeration system for liquefaction of natural g...

previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. as a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. in this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

The work is a primary approach to grab attention on probability of liquefaction hazard in Rangpur City Corporation area. The investigated area of Rangpur was suspected to have high liquefaction potential since the foundation soil consists of loose sandy silt with a very shallow aquifer. Standard Penetration Test (SPT), which follows the general format of the Seed-Idriss simplified procedure for...
