Reliability-Based Design of Earth-Fill Dams to Mitigate Damage Due to Severe Earthquakes

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This research deals with a strategy for the maintenance of geotechnical structures such as earth-fill dams. Standard penetration test (SPT) N-values are frequently used to determine the soil parameters. Firstly, a statistical model for the N-values is determined from sounding test results. In this research, however, Swedish weight sounding (SWS) tests are employed as they are simpler than SPT. Secondly, an indicator simulation is conducted to interpolate the spatial distribution of the N-values, and the results are utilized to find degraded areas inside the embankments and to maintain the embankments. Based on the statistical model for the N-values, the shear strength parameters are derived through the empirical relationships. Then, a reliability analysis of the embankments is conducted considering the variability of the internal friction angle and the seismic hazard.
