Abstract

Through the field in the natural state and, after vibroflotation sand compaction pile treatments on two regions of the static load test of pile and pile stress tests. The Author Had determined the different regions of the vertical ultimate carrying capacity of single pile, and the natural compaction sand pile under two different conditions of pile body side friction are analyzed. After vibroflotation sand compaetion pile treatments, the reinforced concrete filling pile side resistance and end resistance of the pile will be greatly improved, designed by the length shortened to save such projects in foundation of funds.
