MICRO PILE CONSTRUCTION METHOD FOR HORIZONTAL CAPACITY INCREASING

摘要

The purpose of the present invention is to provide a method for constructing a micro pile for improving a horizontal supporting force capable of analyzing movements according to the strength and an installation angle of the micro pile with respect to a horizontal load applied to the micro pile and supporting the horizontal load more efficiently in comparison with an existing method. To achieve the purpose, the method for constructing a micro pile for improving a horizontal supporting force according to the present invention includes (SI) a step of installing a micro pile model previously manufactured on a model testing device wherein a horizontal load applying device is installed according to preset installation conditions; (S II) a step of loading a horizontal load to a head part of the micro pile model installed on a land model using the horizontal load applying device; (S III) a step of finishing the test if the horizontal displacement of the head part of the micro pile model is 10% of the diameter of the micro pile model; (S IV) a step of modeling and analyzing the land model and micro pile model obtained through the model test and actual site ground and a circular micro pile; and (S V) a step of constructing the micro pile at a different angle according to a length rate of the micro pile based on the analysis result of the model test.
