  • Effectiveness of Liquefaction Countermeasures in the 2011 M = 9 Gigantic Earthquake, and an Innovative Soil Improvement Method
    Indian Geotechnical Journal, 2013
    Co-Authors: H. Ishii, H. Funahara, H. Matsui, K. Horikoshi
    Abstract:

    Along with damages caused by tsunamis, huge areas were affected by liquefaction at the wake of Tohoku Region Pacific Coast Earthquake. Demands seem to increase for seismic reinforcement on Soils beneath existing structures not only for the devastated areas, but also for other places where seismic events are expected to occur in near future. In this paper, liquefaction countermeasures are first reviewed of which the authors were in charge during the site Works. Restrictions for the Works were highlighted to show how they were overcome. Effectiveness of the liquefaction countermeasures were also explained through observations at the projected sites. Finally, an innovative Soil Improvement method recently developed by the authors is introduced. The method consists of directional drilling and permeation grouting that can conduct Soil Improvement Work beneath existing structures effectively and economically.

  • effect of mineralogical and physical characteristic of pozzolanic binders on enhancing strength in Soil Improvement Work
    IOP Conference Series: Materials Science and Engineering, 2018
    Co-Authors: Ernesto Silitonga, Harun Sitompul, Rumilla Harahap, Nono Sebayang, Ronal Butarbutar, Iskandar Tambunan
    Abstract:

    Various binders such as pozzolanic binder already known for its ability on enhancing the physical characteristic on concrete or Soil stabilization. Pozzolanic reaction requires several primary factors to provide maximum Improvement on physical characteristic. This research is aimed to identify the effect of the origin characteristics (physical and mineralogical) of pozzolanic binder on increasing the strength on engineering properties in Soil Improvement Work. Two type of fly ashes are utilized in this study with different types of physical and mineralogical characteristic. Laser Granulometric test, and mineralogical test are realized to identify the characteristics of each fly ash utilized. To determine the effect of the binder addition (with different characteristics), several tests are performed such as unconfined compressive test, tensile strength test are realized to identify the effect of fly ash addition. The results show that binder with higher SiO2, Fe2O3 and Al2O3 content produces higher strength.
