520 _aThis thesis deal with (1) constructions oi micro piles in Dot h 11on-displac went and displacement methods (2) load testing the construct d piles to see the behavior of these pile (3) comparison of the actual behavior with the predicted behavior determined by the conventional method. Four micro piles were constructed for testing purposes. All of the piles had the same diameter of 100 mm. Two of them of 17.50 m. length were constructed by the non-displacement method. The other two of 13.85 and 15.00 m. length were constructed by the displacement method. In both methods, one was constructed by the displacement method. In both methods, one was grouted only in the FIRST step, the other was grouted both in the FIRST and SECOND steps. The slow maintained loading tests were carried out after 21 days of pile installing. All piles were tested to failure. From the load test results, it showed that the behavior of the micro piles constructed either by the non-displacement or by the displacement method gave the same results. From the load-settlement relationship, the SECOND step grouting micro piles showed that the pile failed by the yielding of the micro pile tube itself. If the micro pile tube was strong enough to carry the higher load, the failure load would be higher than the actual one. For this reason, the bearing capacity of the micro pile could be improved by the SECOND step grouting.
