Description

Rapid development of a reasonable liquefaction countermeasure for flume channels has been required for the following reasons: 1) several large earthquakes are predicted to occur throughout Japan in the near future; 2) severe damage to flume channels built in liquefiable ground is predicted as a result; 3) flume channels supplying drinking water is an important as lifeline facilities after earthquakes; and 4) tremendous amounts of money would be required to apply the countermeasures in popular use (such as those to prevent liquefaction) to the whole length of long flume channels. Therefore, the authors conducted a study on the application of a countermeasure using sheet-pile with drain to flume channels with the aim of reducing the influence of liquefaction on such structures while satisfying their performance requirements. In this study, the effectiveness of the proposed countermeasure to flume channels was initially confirmed through a series of shaking table tests (1G). This paper describes the details of the experiment and the applicability of the countermeasure to the flume structure as well as the background to this study grounded on performance-based design (PBD) concept.
