TRACE OF LIQUEFACTION AND FLOW SLIDE BASED ON THE GEOSLICER SURVEY

Doboku Gakkai Ronbunshuu C, 2007
1964年新潟地震において，信濃川下流域では液状化に起因する数メートルに及ぶ流動変形が発生した．中には，両岸が20m も狭まった場所があったことも報告されている．著者らは，地盤変形の痕跡が地中にどのように残されているかを調査するため，昭和大橋上流の信濃川左岸河川敷において，地中の地層構造を目視で観察できる地層抜き取り調査を実施した．調査によって，液状化や流動変形に関係する特徴的な地質構造である，貫入した砂脈，水抜け構造，液状化したと考えられる砂層の直上に位置するシルト·砂互層の水平堆積構造の乱れなどが，地層中に残されていることが明らかとなった．また，得られた試料を用いて，物理試験および力学試験を行った結果を合せて報告している．

Stress-strain behavior and residual strength of Petobo sand with variable fines content under consolidated undrained triaxial loading

Jurnal Ilmiah SINERGI
Liquefaction was one of the primary causes of severe ground deformation during the 2018 Palu earthquake, particularly in the Petobo area, where large-scale flow liquefaction resulted in extensive ground displacement.

Liquefaction of coals and maceral concentrates in a flowing-solvent reactor

International Journal of Energy Research, 1994
A flowing-solvent liquefaction reactor with a continuous solvent sweep through a fixed bed of coal has been developed. The reactor is heated by computer-controlled direct electrical resistance heating, allowing the application of variable heating rates between 0.1 and 10 K/s to temperatures up to 450 °C and holding times at peak temperature between ...

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...
