REARCH ON THE SPECIAL NATURE OF BEARING CAPACITY OF BORE PERFU SION PILES IN MUD-ROCK BASE BY DYNAMIC AND STATIC TESTS

Base on the testing resulting of single pile vertical compressive static loading experiment and high strain dynamic test of three big-diameter bore perfusion pile in a project of Xi' ning area, The relatively consistent results have been obtained by means of analysis and research in some suitable conditions. But the results have respective characters because of different testing principle and analyzing methods. It proves that comparison between dynamic test and static test in the same project can be provable and complementary to each other. The two test results show the special nature of bearing capacity and destructive mechanism of medium-long diameter bore perfusion piles in mud-rock base, Which will offers constructive suggestion on design,construction and deeper research as well as great reality significance for Great West Development.
