Application of powerful digging reinforcement skill in sea-filling basement construction;

Analiysising to physical mechanics property,particle composition,chemical analysis of iron tailings,theoretical inference and necessary bench test and comercial test,the reliabitity has been proved by theoretical and practice on road surface material,insteading riversand concrete,and roadbase backfill material,as technology dates of application.

Through practice of filling the roadbed construction of section II on Cen Wu highway in Guangxi Province, this paper explains the construction technology and method of filling roadbed with sand high liquid clay.

On the quality control of the expansive soil improved by lime subgrade filling;

The influences of cycles of freezing in winter and thawing in spring andsubgrade filling on 3~# landslide are analyzed with numerical method.

In order to ensure filling quality of the subgrade,enhance integrity stability of the subgrade,it accordes to detailed investment and combines with earth work test,provides scheme of adopting strong decomposed rock to get subgrade filling,and gets filling technology test,gets complete success,accumulates subgrade construction experiences of the mountain area expressway.

Discuss on moisture control of roadbed filler;

The application of roadbed filler in double line engineering of Wuxiang;
