EXPERIMENTAL STUDY ON BEARING CAPACITY AND SETTLEMENT OF BORED PILES IN LARGE THICKNESS LOESS REGION
Through the large tonnage static load tests of the 6 bored piles of a super high-rise buildings in Qingyang area, comparing the results of the bearing capacity and settlement performance of the six long piles and short piles, the results shows that the effect is not obvious to improve the bearing capacity and reduce settlement through increasing the pile length, when the vertical compressive ultimate bearing capacity is less than 14 000 kN, so test pile is very important; In the process of calculating the settlement of pile body, the compression of pile endpoint soil should be considered only when the load is greater than the critical load; the composite coefficient of long pile and short pile were 0.48 and 0.46 by using simplified methods for calculating the pile body compression, so the standardized coefficient 0.5 is larger.
