在黄土丘陵地区建筑土壩,所利用土料中,往往遇到颜色深红,近似于半固体的坚实粘土,这种粘土不论在开挖与压实上都有一定的困难。所以规范上都建议避免采用肥粘土作为土壩的建筑材料。然在山区丘陵区,这些土料分布还很广,群众都认为这种土料是很好的材料,因为这种土料在细致处理、压实后,坚硬如石,具有高度的不透水性。所以利用这种土料作为心墙、截水墙填筑壩身都是可以的。因此提出以作
In the construction of earth mounds in the loess hilly region, the soil materials used often encounter crimson color and are similar to semi-solid, solid clay, which has some difficulties both in excavation and compaction. Therefore, it is recommended to avoid the use of fat clay as earth dam construction materials. However, in the hilly areas of the mountains, the distribution of these materials is still very wide, the masses believe that this material is a very good material, because this material in the meticulous treatment, compacted, hard as a stone, with a high degree of impermeability . Therefore, the use of this material as the heart of the wall, cut off the wall filling dam body are possible. Therefore proposed to make
