【Abstract】 The technique of spiral pressure and cementation is a new process of forming piles. By using mathematical statistics, a certain reliable analysis for pile loading capacity has been done and been compared with the results of piles in practical engineering tests. It shows from the analysis that this kind of piles of using the technique of spiral pressure and cementation has the advantages of fast speed of forming piles, close compactibility,great loading capacity and other comprehensive benefits as well.更多还原
