希尼尔水库大坝无水碾压填筑施工

Dry roller-compacted construction of dam for Xinier Reservoir

通过碾压试验、施工复核及大坝运行观测,得到了大坝的设计填筑标准,从而确定了经济合理的压实方法,包括压实机械选型、机械参数、砂砾料加水量等。同时,制订了压实质量控制方法,研究和改进了填筑的施工工艺和措施,优化了大坝体型及施工碾压参数,节约了投资。

Based on the roller-compacted test, check on construction and observation during operation, the fill-criteria of the design for the dam is obtained, and then the economic and reasonable roller compacted method, including selection of the roller, mechanical parameters, watering amount for material of sandy gravel etc., is determined as well. Simultaneously, the quality control method for the compaction, the construction technologies and measures and the roller-compacted parameters are studied and optimized, in this way the investment is saved at last.
