素混凝土桩螺旋压灌技术及其应用

Techniques of Spiral Pressure and Cementation for Concrete Piles and Its Application

混凝土桩基的螺旋压灌技术是一种新的成桩工艺 ,用数理统计的方法对旋压混凝土桩基的承载力进行了可靠度分析 ,并与工程实例桩基检测结果比较 .分析表明 ,采用螺旋压灌技术 ,成桩速度快、桩身密集性好、桩承载能力强。

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.
