RAPID LOAD TEST METHOD FOR PILE BY USE OF SEGMENTAL UNLOADING POINT CONNECTION METHOD
Disclosed is a rapid load test method for a pile by use of a method resulting from extending a well-known SULP method, wherein a rapid load test is implemented on a pile head more than once in the manner of changing a drop height h of a weight, with the pile instrumented with strain gages and accelerometers at more than one depth level, followed by the processing of obtaining a rapid load Frapid -pile displacement w relation for each pile segment for each time of the rapid load test using measurement data measured by the strain gages and the accelerometers, of obtaining a soil resistance Rs.ii-pile displacement w relation on each pile segment for each time of the rapid load test, of calculating an unloading point that can be a point of maximum displacement of the pile, together with an unloading point load RuLp at that moment, and of obtaining a static soil resistance Rw-pile displacement w relation on each pile segment by use of an Unloading Point Connection method using the calculated unloading point and unloading point load RuLp for each time of the rapid load test. Accordingly, an analysis on a load-displacement relation is performed by use of a load transfer method with respect to the whole pile, using a nonlinear model of the thus obtained soil resistance on each pile segment.
