摘要
南四湖二级坝第三节制闸扩建工程地基有液化的可能,根据勘探资料,对可液化地基的加固方法进行了比较;通过灌浆加固后取样的水泥含量、无侧限抗压试验等对比研究,对纯水泥浆和水泥与黏土等4种不同配合比灌浆材料的可行性进行了研究,推荐了实际工程加固的施工工艺参数。工程实施情况表明,选择的灌浆材料是可行的。
In consideration of the fact that ground liquefaction might occur in the second floodgate extension project of Nansihu grade- Ⅱ dam, the consolidation methods for the liquefiable ground were compared based on the investigated data. By cement content and unconfined compression tests on samples after grouting consolidation, a feasibility study was performed on 4 kinds of grouting materials, such as pure cement mortar, cement and clay, etc. with different mixing ratios, and rational construction parameters were recommended. The results show that the recommended grouting materials are feasible.
