Field experiment and engineering application of cement2modified soil fill ing construction

The quality o f cement2modified soil filling constructio n is an im po rtant facto r affecting the stability o f channel slope in the ex pansiv e rock( so il) reg ions. Accor ding to the replacement situation of cement2modified so il in t he South2t o2Nor th Wat er Di2 v ersion Project, a new cement2modified so il filling co nstr uction metho d, concentr atio n f ield mix ing metho d, w as pr oposed based on the analysis o f the field roller com pactio n experiment results of road m ix ing metho d and plant mix ing method. The new meth2 o d can ov ercome the disadvantages of road mix ing metho d and plant mixing metho d, and has been successfully applied to the ce2 ment2modified soil filling co nstr uct ion in t he Middle Route of South2to2Nor th Water Diversion Pro ject, w hich can pr ov ide r efer2 ence fo r the similar eng ineer ing pr ojects.
