It also includes a consideration of possible alternatives, such as a concrete gravity dam or an earth-fill embankment dam.
还要考虑到可能的备选方案，比如是选择混凝土重力坝还是选择填土筑堤大坝。
2
Taking the expanding project of Duanjiaxia homogeneous earth-filldam for an example, methods of seepage calculation about expanded dam are discussed.
以段家峡均质土坝扩建工程为例，探讨大坝扩建后其渗流计算方法。
3
Light loam and medium loam with less clay particles as fillearth had been extensively used in the construction of hydraulic filldam in the Loess Plateau region.
