碎石改良高液限红粘土击实性能试验研究
Experimental Study on Densification Performance of High Liquid Limit Red Clay Modified with Crushed Stone
摘要
Abstract
In order to study the effect of crushed stone on the improved high liquid limit red clay, two groups of crushed stone with different diameters were selected and mixed into the test soil sample with different proportion. Then a compaction test is implemented on improved test soil sample. The high liquid limit red clay that improved by different admixture ratio of rubble have different change rules of compaction curve ,which indicates that the optimum moisture decreases and the maximum dry density increases while its admixture increases. Both the clayey gathering effect of the high liquid limit red clay and the diameter of crushed stone have influences on the effect of soil improving. Although the maximum dry density of two groups is increasing with the rise of admixture, the trends of both are different, and the improved effects of both are different.关键词
