如铺土厚度，碾压遍数，碾压机具，粘土的最优含水量，干密度。
As the thickness of spread clay, The Times of grind, the machine of grind, the best containing water amount of clay, the dry density.
采用标准试验方法求得筑坝用煤矸石的最大干密度和相应的最优含水量。
Normal test method is employed to explore the relationship between dry density and optimum water content of coal gangue used in daming.
得出干于最优含水量填土的抗拉强度高，极限变形也大，加荷速率对饱和土的抗拉强度没有什么影响。
The conclusions are as follows: When the Water content of filling soil is lower than the optimal one, the tensile strength is greater and the limiting deformation is larger.
含水量对改良土的工程性质影响很大，因而在工程施工中应使改良填料的含水量尽可能达到最优含水量。
The ratio containing water influences much largely for improved soils, so it should be keep at the optimal ratio during construction of engineering.
