摘　　要：对于水利水电工程建筑,不良地基对建筑物的影响主要表现在基础的沉陷量过大或不均性,基础渗漏量或水力坡降超过容许值,地质质量差,抗滑稳定系数小于设计规定值。由于水利工程地基的工程地质条件千差万别,有时需要在不良的地基上建设水利工程,但不良地基直接影响着水工建筑物的安全,只有对其进行可靠的处理后,才能确保水利工程的安全运行。As for the structure of water conservancy and hydroelectric projects,the influence of unfavorable geological conditions on structure often displays a large foundation settlement and uneven settlement,exceeding allowable value for foundation seepage or hydraulic gradient,bad geological condition and low stability coefficient of anti-tension and sliding.Because the geological conditions on the various hydraulic engineering foundations vary greatly and unfavorable conditions will effect on the safety of the project,it’s necessary to build water projects on the unfavorable foundation sometimes and important to treat them to ensure the water projects works safely.
