摘　　要：沙坝坝体材料渗透性强,允许渗透比降很小,在渗流控制上存在一定难度。通过李家梁水库的工程设计及运行中出现的问题对沙坝的渗流控制进行探讨,说明沙坝在渗流控制方面采用的一般工程措施。permeability of sand dam material is high, and the allowable seepage gradient of the material is very small. Therefore, there are some difficulties in the seepage control of the material. In this paper, the seepage control of sand dam is discussed through issues occurring in engineering design and operation of Li Jialiang reservoir. The general engineering measures for seepage control of sand dam are described.
