Study on Large-scale In-situ Immersion Static Load Test for Bearing Behavior of Collapsible Loess ile Foundation
large-scale in-situ immersion static load test has been conducted on bored piles (pile diameter: 0.8m, pile length: 18m, side length of immersion pit: 20m) at self-weight collapsible loess site combining Xian East Second Ring Road-North Second Ring Road Overpass Project which is a project funded by World Bank loan. Based on static load test of pile foundation in overpass project without immersion, before immersion and after immersion and comparative analysis of ultimate bearing capacity and settlement of pile foundation, this paper analyzes strength value of negative friction resistance of pile foundation and its distribution law. Research results have important theoretical value and guiding significance for the design and construction of bridge pile foundation in loess area.
