Abstract:
In order to research the effect of the content of mud rock on intensity index of Xigeda filling, the shearing test for Xigeda roadbed of the different content of mud rock laminated best well by the 16 t and 18 t road roller was carried out, the CBR test of the Xigeda filling of the different proportion of the mud rock and sandstone in indoor and random commix in outside was carried out, the test of degree of compaction for Xigeda roadbed of the different content of mud rock was carried out by the 16 t and 18 t road roller。The results show that: the content of mud rock affect little to internal friction angle φ and internal cohesion c,so φ adopt 32° and c adopt 42.571 kPa in designing to 16 t road roller; the content of mud rock affect little to φ, but affect large to c, so φ and c adopt little in designing to 18 t road roller; the relation of CBR and the content of mud rock is index movement; the degree of compaction of Xigeda filling increase as well as the content of mud rock increase. 5 tabs, 4 figs, 11 refs.
