| 摘 要： | 糯扎渡心墙堆石坝最大坝高261．5m，因此土料除需满足防渗要求外，还须有较好的力学性能。根据砂、泥岩的风化程度与土料的不同性质，土料可分为坡积层、构造残积层、强风化层和混合料，通过对各层进行分析，以及根据试验资料和以往工程经验，最终设计采用掺砾料作为心墙料。

| Abstract: | According to the exploration and test information of the borrow areas, this article presents the basic property and peculiarity of the imperious earth. As a rockfill dam of nuozadu hydropower project is 260 m high, core wall earth must have better impermeability and mechanica property, so it is necessary to take designing measures to mix gravel into earth. |
