摘　　要：通过对水泥材料、特定温拌剂的添加量、温度拌合技术和拌合摊铺技术等方面的优化分析,探讨在超荷载条件下堤坝弹性恢复能力的恢复机制.结果表明:改进的水泥混合料拌合成型技术所修筑的堤坝在超荷载下抗荷载强度提高明显,弹性恢复机制可以提高成型堤坝在超荷载下的弹性恢复能力.The mechanism of the dam elastic recovery ability under over load was discussed by the optimal analysis of the cement material,amount of special warm mix additives,mixing temperature and mixing paving technology.The results show that the strength of the dam constructed by the improved mixing technology of cement mixed material increases significantly under over load,and elastic recovery mechanism can improve the elastic recovery ability of the formed dam under over load.
