Liquefaction Demonstrations - a Student Project


The recent increase in catastrophic earthquakes (latest India Gujarat Earthquake, 2001) and the repeated evidence of ground failure due to liquefaction motivated this student research project. Liquefaction is a soil mechanics problem that often impacts structures that are supported on saturated sand deposits. The large deformations of the foundation soils typically cause major failures of civil engineering structures. This project involved research of the liquefaction phenomena and the impact experienced on select recent earthquakes. Additionally, the design of an experiment demonstration will be completed during the academic year. The device will be a feature laboratory demonstration to inspire students interested in earthquake engineering. A student was guided to research the literature on soil liquefaction and performed simple exercises on how liquefaction occurs. Once the student developed a working knowledge of the liquefaction phenomena the design of a liquefaction demonstration device was initiated. The student developed design drawings (AutoCAD and to scale) to be used in building the device in conjunction with the departmental machinist.
