| 英文摘要 | This study was part of a preliminary safety assessment for a real project of existing bridge piles passing through beaded karst caves threatened by a nearby newly built embankment. To investigate the severity of the effect of the embankment on the performance of these piles, a series of reduced-scale model experiments of piles considering different cave numbers (n = 0, 1, 2, and 3) near surcharge loads were designed with a similarity ratio of 1:35. Two phases of loading, the vertical loading atop the pile and nearby surcharge loading, were imposed successively to explore the vertical bearing characteristic and lateral response characteristic of the piles passing through beaded karst caves. The effects of cave number, vertical load atop the pile, and nearby surcharge load on the responses of pile and soil were clarified and several fitting functions were presented to characterize the variations of responses with different cave numbers and nearby surcharge loads. The results and conclusions can provide a reference for the design and safety assessment of bridge piles in karst terrains. |
