摘　　要：通过计算分析 ,认识到深埋桩有无穷多组解 ,用简化的“等值梁”理论设计计算深埋桩却只有一组解 ,作为一种设计计算方法 ,其缺陷是很明显的。本文提供了一种优化设计方法 。An optimal-design method for deep piles is proposed in the paper;the piles are deep embedded and supported.The deep pile really is a kind of pile between the shallow pile and the cantilever pile;it has many solutions but the late other two kinds of pile only have one solution.It is given just one solution when using a simplified method for deep piles;it is shown that the project design cannot sure be optimized It is deep discussed on the theory of the optimal?design method for deep piles.The computing results show that the results of the proposed method are in quite agreement with the test measurements.
