摘　　要：提出了对影响坝体稳定的薄层软弱夹层采取混凝土桩加固的办法。该法可增大夹层的抗剪能力，达到坝体连同部分坝基沿软弱夹层的抗滑稳定安全，避免了因采取大开挖造成的投资加大、工期加长的弊端。The concrete pile method used to reinforce the weak intercalated stratum affecting dam stability is suggested in this paper.This method can increase the shearing strength of interca lated stratum thereby achieving the anti-slide,stability and safety of the dam body together withpart of dam foundation along the weak intercalated,tratum. Accordingly,the disadvantages of increasing investment and prolonging construction duration caused by adopting the large-scale excavation can be avoided.
