膨胀岩渠坡处理措施施工工艺研究

南水北调中线一期工程总干渠新乡潞王坟膨胀岩试验段渠坡主要采用换填黏性土料、土工格栅、土工袋这 3 种不同处理措施。针对这 3 种处理措施，比选、研究了在不同碾压机具、铺土层厚、碾压遍数等条件下的压实效果。结合室内试验分析，提出了不同处理措施的施工碾压参数和施工压实质量控制指标。试验成果为合理制订设计方案，施工单位选取施工机具、碾压施工参数，以及施工质量控制等工作提供了有效的依据。

Construction Technology of Treatment Measures in Swelling Rock Slope

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.
