從理論上深入論證分析了堆石流變的機理,對于堆石這種非自然存在的散粒材料,其流變與土體的次固結相類似,產生堆石流變的主要原因是顆粒破碎細化、滑移充填孔隙所致。There is certain relation between the secondary consolidation coefficient and the secondary primary settlement ratio, that is, when the secondary primary settlement ratio is less than 1, variation of secondary consolidation coefficient is very small, which even can be neglected ; with the increase of the secondary primary settlement ratio, variation of secondary consolidation coefficient increases at the same time
次固結系數與土的次主沉降比有一定關系,對于次主沉降比小於1的土,次固結系數變化很小,可以忽略不計;隨著次主沉降比的增大,次固結系數的變化也增大。Coefficient of secondary consolidation
