Experimental research on vertical bearing properties of basegrouting bored castinplace pile

Basegrouting pile after construction is a new technique that has been maturely developed recently in the region of foundation pile construction. The technique can both improve the bearing capacity of pile and decrease the pile top subsidence obviously and meanwhile,the bearing properties of foundation pile change. Based on the results of vertical static loading test of the two single piles with and without basegrouting,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.Therefore it is instructive for design and construction of similar piles.
