Re-liquefaction resistance of lightly cemented sands

Canadian Geotechnical Journal, 2022
The re-liquefaction resistance of cemented sands under multiple liquefaction events such as pre-shock, main-shock, and after-shock earthquakes is a complex phenomenon because the response may alter due to bond breakage. A series of multistage liquefaction–re-consolidation soil element tests under undrained stress-controlled cyclic loading condition ...

Liquefaction resistance behaviours of gravel steel slag

European Journal of Environmental and Civil Engineering, 2020
Due to the continuous scarcity of sand and gravel under environmental protection policies, a new geo-backfill material with the good liquefaction resistance is urgently needed.

Liquefaction resistance of sand amended with biochar

Géotechnique Letters, 2020
Biochar is a solid carbon material produced by heating organic biomass in the absence of oxygen through a process known as pyrolysis. Scientists and policy makers have recognised its potential role in carbon sequestration, reducing greenhouse gas emissions, renewable energy, waste mitigation and as soil amendment.

Effects of Permeability on Liquefaction Resistance and Cone Resistance

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
Sands and silty sands with the same liquefaction resistance can have significantly different hydraulic conductivity and coefficient of consolidation. Numerical simulations of cone penetration resistance taking into account the effects of silt content and consolidation characteristics show that the penetration resistances are significantly affected by ...

Resistance to Liquefaction Due to Sustained Pressure

Journal of the Geotechnical Engineering Division, 1977
It has long been recognized that clays increase in strength with time due to consolidation and secondary compression; however, the fact that sands can increase in strength after periods of sustained loading is not so well known. Recently several engineers have suggested that the liquefaction characteristics of in-situ sand deposits are influenced by ...

Liquefaction-Resistant Foundations for Residential Buildings

2013
On 4 September 2010 a Magnitude 7.1 earthquake struck the Canterbury region of New Zealand, centred 40km west of Christchurch and 10km deep, causing significant damage. On 22 February 2011 an aftershock of Magnitude 6.3 struck directly beneath the southern suburbs of Christchurch.

Liquefaction resistance of sand reinforced with geosynthetics

Geosynthetics International, 2008
This paper describes an investigation into the performance of geosynthetics in enhancing the resistance to liquefaction of medium dense (Dr = 50%) sand deposits. Cyclic torsional shear tests were carried out on 99 laboratory test specimens under a confining pressure of 98 kPa and a loading frequency of 0.1 Hz.

Corrosion-Resistant materials for coal liquefaction systems

Journal of Materials for Energy Systems, 1985
The corrosion response of alloys in various process environments in coal liquefaction pilot plants is discussed. Causes of corrosion and limiting conditions (such as temperature, pressure, and fluid velocity) are addressed. Solutions and needed development are emphasized.

Liquefaction resistance of bio-cemented calcareous sand

Soil Dynamics and Earthquake Engineering, 2018
Abstract Coral reefs and other calcareous deposits may experience various types of significant dynamic loading, such as those from waves and earthquakes. When submerged and subjected to earthquake loading, the potential for liquefaction of calcareous deposits may cause a loss of human life and property; however, few studies have evaluated the ...
