Abstract: There are three treatment measures in the swelling rock slope of the Luwangfen test section of Middle Route of South-to-North Water Division Project, including geogrid with marlite, soilbag with marlite, replaced backfilling clay. The compaction effect of these methods is studied under the conditions of different machines, different layer thicknesses, different roller compaction times, and so on. Then in combination with results of indoor test, the compaction parameters and the quality control indexes are provided. The test results provide a basis for design, machine choice, compaction parameter and construction quality control index.
