Seismic Damage and Analysis of the Xiker Earth Dam During the 2020 Jiashi Earthquake, Northwestern China

open access: yesFrontiers in Earth Science, 2021
The 2020 Jiashi Mw 6.0 earthquake occurred at the Kepingtage fold-and-thrust belt in the South Tianshan front, Northwestern China. The ground shaking caused extensive co-seismic deformation of the Xiker dam in the meizoseismal area.

Liquefaction Resistance of A Partially Saturated Sand

open access: yesSoils and Foundations, 1989
ABSTRACT Cyclic torsional shear tests on hollow cylindrical specimens were conducted to investigate the effects of degree of saturation on the undrained cyclic shear strength (liquefaction resistance) of air-pluviated Toyoura sand at a relative density of 60 percent. The tests showed that (1) the liquefaction resistance increased significantly with a

Flow Potential of Sand During Liquefaction

open access: yesSoils and Foundations, 1998
In order to quantify the tendency to flow characteristics of sandy soils, the maximum value of excess pore water pressure ratio developed during undrained monotonic loading test was taken as an index property and defined as flow potential. Triaxial compression tests, triaxial extension tests and simple shear tests on Toyoura sand were conducted by ...

Sand Liquefaction Due to Irregular Excitation

open access: yesSoils and Foundations, 1972
ABSTRACT An electro hydraulic servo type loading system was incorporated into the conventional triaxial shear test apparatus so that any desired form of load pattern can be applied to soil specimens. In applying this system to the study of liquefaction of saturated sands, a difficulty was encountered in keeping the applied stress perfectly controlled

Assessing liquefaction susceptibility of fibre-reinforced sand.

open access: yes, 2021
Very loose and loose sands may be susceptible to liquefaction when they are saturated and subjected to undrained loading. Adding discrete flexible fibres into sand is a promising technique to improve their mechanical properties, making sands stronger, in
