| 中文摘要:针对南疆砂砾石填筑大坝进行碾压试验，验证坝体填筑设计压实标准的合理性、检验22 t自行式振动碾的适用性及其性能的可靠性。本试验主要采用室内相对密度试验、现场的碾压测定出碾压遍数、碾压沉降及相应密实度及其他试验参数，通过试验参数列表、试验参数包络线图与设计标准值的比较，得出最佳砂砾石填筑方案，同时也确定大坝填筑时的施工碾压控制参数，从而确保了工程质量。 |

| Abstract:The filling and compacting tests are made for sand gravel filled dam in southern Xinjiang to verify the rationality of dam filling design compaction standard and test the 22t self-propelled vibration roller on the applicability and the performance reliability. The test determined the number of rolling passes, compaction settlement, the corresponding compactness and other parameters mainly by indoor relative density test and field RCC. By comparing the list of test parameters, test parameters enveloping line diagram and design standard values, the best sand gravel filling scheme is obtained and the construction RCC dam filling control parameters are also determined to ensure the engineering quality. |
