摘要： 在沿整个圆周均匀配筋与局部均匀配筋相结合的条件下，提出一种钢筋混凝土支护桩配筋的新实用方法,构建了一个函数数表,同时提出修正值公式。通地四个实例的计算表明，新方法可节省钢筋14%~31%，而仍保留仅沿整个圆周均匀配筋的优点。

Abstract: Based on the view point of the uniform reinforcement along entire circular section combined with partial uniform reinforcement. There is a new method to calculate reinforcement for R.C. Retaining Piles with circular section, in which the function table and the correction formula are included. The results shows that the application of new method the steel bar is saved about 14~31% with the advantage of uniform reinforcement alone entire circle.
