Pile capacity distribution analysis for SLT with reactive system

Abstract

In the paper, the analysis of the bearing capacity of the pile and the redistribution of the load on the pile toe and shaft was carried out. The tests were carried out by a static load test (SLT) incrementally increasing the compressive force on the test pile, and the tension force on the anchor piles. The test system consisted of one test pile and two anchor piles with a reaction beam. Two tests were conducted according to the same test program, where the test piles were of the same length, while the length of the anchor piles in the second test was increased. In the first test, the anchor pile failed, while in the second test, the test pile failed. Based on the achieved limit values of settlement of the test and anchor pile, the bearing capacity of the test pile at the toe and shaft was determined. Subsequently, a CPT test was carried out and the bearing capacity was calculated according to the LPC-CPT method.
