From wet density, water content and maximum dry density, compute compacted dry density and degree of compaction and check it against specification for earth-rock dam and embankment fill.
计算填筑料干密度与压实度,判定压实质量是否达标
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Relative compaction | Rc = Pd / Pdmax ≥ design value (e.g. 0.98–1.00) | GB/T 50123 Standard for soil test methods; SL 274 Design code for rolled earth-rock fill dams |
| Maximum dry density | Obtained from compaction (Proctor) test | GB/T 50123; DL/T 5129 Construction spec. for rolled earth-rock dams |
土石坝填筑密度控制工具用于土石坝填筑施工质量评定。根据实测湿密度、含水量计算干密度,与设计干密度比较得出压实度,并结合最优含水量偏差综合判定填筑质量是否达标,是土石坝施工质量控制的关键工具。
