Artificial Dig-hole Pile Single Pile Bearing Capacity Experiment And Dislacement Simulation Analysis

This paper is based on the jinzhou petrochemical artificial dig-hole pile bearing capacity research subject, introduces the stress mechanism of enlarged end of pile, and combining with the situation simply introduces the construction technology and the quality safety requirements. In the two piles(straight-wall pile, enlarged end of pile) conducted on-site static load test, through observing the test data of the static load test of the loading and unloading process, acquisiting and processing the test data draw load-settlement curve, Comparison of straight-wall pile and enlarged end of pile top settlement changes; Use Q—S curve and two kinds of pile settlement changes to analyze the load-settlement rules; Analyze the difference of artificial dig-hole straight-wall pile and enlarged end of pile in the bearing capacity and the deformation, Using finite element software ANIDA model to simulation of the influence of the load on the pile settlement and pile by loading the stress and deformation characteristics.
