Through static load test, inforcement stress tests and other tests on uplift pile in Shenyang sand area, study the uplift pile bearing capacity and lateral friction, and get the following conclusions:according to the soil division by stratigraphic to determine the lateral friction is more reasonable than the soil division by lithology; before and after grouting, the lateral friction enhancement factor is about 1.15 to 1.62 in the enhanced part; the effect of branches and plates can partly improve the lateral friction, but also limit the lower lateral friction in certain length range of the pile.
