Research on the Method to Detect Vertical Bearing Capacity for High-Piled Wharf Piles Based on Prototype Test

摘要

There are many mature methods to detect the bearing capacity of singlepile. But for high-piled wharf piles, as they are parts of high-piledwharf, and complex structures are built on them, for these non-free endpiles, there are no effective and feasible bearing capacity detectionmethods at this stage. In this paper, regional heap load method to detecthigh-piled wharf piles capacity was proposed, and this method did notdestroy the original structure. The high-piled wharf piles capacityprototype testing was carried out, and the deformation displacement ofwhile high-piled wharf, the displacement of piles, and the strain ofstructural elements were tested under grading loads. Also the numericalmodel was established to analysis the bearing capacity of high-piledwharf piles, and the numerical model was corrected by theexperimental results. Then the whole prototype test process wassimulated using the modified mathematical model, finally the verticalbearing capacity of high-piled wharf piles was determined by comparednumerical and experimental results.
