Comparative Study on Behavior of Vertical and Batter Piles in Lateral Spreading Soil
https://orcid.org/http://orcid.org/0000-0002-7900-3890
Liquefaction induced lateral spreading of soil is reported to be one of the primary causes of failures of pile supported bridges and structures during major earthquakes (1964 Niigata, 1989 LomaPrieta and 1995 Kobe). The present study investigates the performance of single piles subjected to lateral spreading displacement through probabilistic approach. Beam on non-linear Winkler foundation method has been adopted to evaluate the pile response. The prediction models for pile response (maximum bending moment) are developed using response surface methodology for piles of different batter angles (0°, 10° and 20°) and slenderness ratios (15, 20 and 25). The probability of failure of various soil-pile systems is then evaluated using Monte Carlo technique. The results indicate that positive batter piles are effective in restricting the bending moment compared to vertical piles, and the behavior of piles subjected to lateral spreading is majorly controlled by the thickness of surface crust overlying the liquefiable soil.
