Abstract

Abstract

Based on the results of vertical static loading test of piles in the high-rise building, the influence of base-grouting on the bearing properties of pile is revealed by analyzing its properties of vertical limiting bearing capacity, axial load transmission and tip and shaft resistance of pile, load transfer performance and bearing mechanism is discussed in detail. In the end, a conclusion is deduced that the base-grouting is inevitable development trend of bored piles in Shanghai soft clay area.
