On the 4 th of June, 2000 and 12 September, 2007, Ratu Agung Sub-district, Indonesia experienced significant damage due to liquefaction after earthquakes. Therefore, this study aims determine Liquefaction Potential Index in area. Data shear wave velocity (Vs) was collected using Multichannel Analysis Surface Wave (MASW) method. The measurement location set up on a grid 32 observations points wi...

Creosoteand chromated copper arsenate (CCA)-treated wood waste and untreated southern pine wood were liquefied with phenol and sulfuric acid. The effects of sulfuric acid content, liquefaction time, liquefaction temperature, and phenol to wood ratio on liquefaction rate (i.e., wood residue content) were investigated and analyzed by analysis of variance (ANOVA). The results showed that both creo...

The parts of Yogyakarta-Bawen Toll Road Indonesia, based on the geological agency’s liquefaction susceptibility map are located moderately susceptible to soil. This can be a preliminary indication as it roughly indicate potential. However, cannot illustrate actual condition in detail its inputs macro parameters (geological and seismicity factors). existence silty sand sand, earthquake sources, ...

Pulverized Wyoming subbituminous coal was beneficiated by low-pH oil agglomerationat CONSOL to prepare the coal for direct liquefaction. Conventional cleaning is not veryeffective in cleaning this coal; for example, conventional oil agglomeration only givesabout 20% ash rejection. To improve ash rejection, the coal-water slurry was acidifiedto a pH of about 0.5. Oil agglomeratio...

This paper investigates the effect of micropile installation into saturated sandy soil by means of finite element method. The obtained results from numerical modeling are compared with the received data from the site. The validation of software has been done by simulating standard penetration test. The effect of some changes in spacing (3m, 1.6m and 0.8m) and injection pressure (1cm, 2.5cm, 5cm...
