【Abstract】 The examples of construction show that the compactive effect of the surrouning and underlying soils due to the construction of pile foundation enhances the pile-bearing capacity,The author proposes to use small-diameter-pile to enhance the pile-bearing capacity,to lower the cost of foundation and to increase economic benefit in accordance with the pile vertica bearing capacity determined ty the pile static load test.更多还原
