42、)含水量。土中含水量对压实效果的影响比较显著。当含水量较小时,由于粒间引力使土保持着比较疏松的状态或凝聚结构,土中空隙大都互相连通,水少而气多,在一定的外部压实功能作用下,虽然土空隙中气体易被排出,密度可以增大,但由于水膜润滑作用不明显以及外部功能不足以克服粒间引力,土粒相对移动不容意,因此压实效果比较差;含水量逐渐增大时,水膜变厚,引力缩小,水膜起润滑作用,外部压实功能比较容易使土体相对移动, 压实效果渐佳;土中含水量过大时,空隙中出现了自由水,压实功能不可能使气体排出,压实功能的一部分被自由水所抵消,减小了有效压力,压实效果反而降低。然而,含水量较小时,土粒间引力较大,虽然干密度较小,但其
43、强度可能比最佳含水量时还要高。可是此时因密实度较低,空隙多,一经饱水,其强度会急剧下降。这又得出一个结论:在最佳含水量情况下压实的土水稳性最好。seoftheaccident,inadditiontoitsownresponsibility,andaccountability;18open-pitmineprotection,includingbarbedwireorfencesagainstmoredrillingorheadtovisit;19winteropenpitminestaffcottoncapshavesmallears,summerrainhattopreventprejud

48、sport,con最佳含水量和最大干密度是两个十分重要的指标,对路基设计和施工很有用处。2)土类在同一压实功能作用下,含粗粒越多土,其最大干密度越大,而最佳含水量越小。3)压实功能同一类土,其最佳含水量随压实功能的加大而减小,而最大干密度则随压实功能的加大而增大。当土偏干时,增加压实功能能对提高干密度的影响较大,偏湿时则收效甚微。故对偏湿的土企图加大压实功能的办法来提高土的密实度是不经济的,若土的含水量过大,此时增大压实功能就会出现“弹簧”现象。另外,当压实功能加大到一定程度后,对最佳含水量的减少和最大干密度的提高都不明显了,这就是说单纯用增大压实功能来提高土的密度未必合算,压实功能过大还会破坏土体结构,效果适得其反。4)压实土的厚度在相同土质和相同压实功能的条件下,压实效果随压实厚度的递增而减弱。试验证明
