【Abstract】 Form the result of static load tests for single pile, the shape of load versus sinking curve, the distribution of axial force along piles body and the function of friction resistance force around piles for under reamed bore piles with large diameter taking gravel ground as support of piles end are studied. At the same time, some researches are also paid on its bearing capacity.更多还原
