Benchmarking Recently Developed Procedures for Designing Pile Foundations in Laterally Spreading Ground

Recent earthquakes in Chile, New Zealand, and Japan provide an opportunity to benchmark recently developed Caltrans design procedures for bridge piles that will withstand liquefaction and lateral spreading. Specifically, case history data from the 2010 Chile earthquake, the 2010-2011 earthquake swarm around Christchurch, New Zealand, and the 2011 Tohoku earthquake in Japan were collected. The data collected included soil information, structural details, and post-earthquake damage observations. From the collected case history data, one bridge with the most complete data set from each country was chosen for complete analysis. The Mataquito Bridge in Chile, the South Brighton Bridge in New Zealand, and the Mihama Bridge in Japan were selected. Within this report, pile foundations are analyzed for the three identified bridges with the proposed Caltrans design procedures using the collected and screened case history data. The computed results are compared with actual bridge pile performance. The comparisons are used to suggest potential refinements to the Caltrans design procedures. The comparisons show that, in general, for the three case histories considered, the Caltrans design procedure worked well. While there were some variations in agreement between the calculated and observed performance, all of the bridges were “predicted” to perform reasonably well, and all were observed to be in service soon after the earthquakes. Recently, much more case history data has become available from the three earthquake events, some with observed poor performance. This broader set of case history data should be analyzed to better refine and improve the Caltrans method further, including bridges with good and poor performance.
