在本讲座第一讲中已提到,在相同压实功能作用下,同一种土的干容重随土中含水量的不同而变化。对于细粒土而言,存在着这样一个关系:在某一含水量时土的干容重达到最大值,并称之为最优含水量和最大干容重。在工程实践中,我们就应用这一原理找出土的最优含水量并在施工中加以控制,使得填土在特定的压实功能之下达到最佳的压实效果,并根据
As mentioned in the first lecture of this lecture, under the same compaction function, the dry weight of the same soil varies with the soil water content. For fine-grained soil, there is a relationship where the soil’s dry weight reaches a maximum at a certain water content and is called the optimum moisture content and the maximum dry weight. In engineering practice, we apply this principle to find the optimal soil moisture content and to control it during construction, so as to achieve the best compaction effect under certain compaction function.
