摘　　要：所研发的高性能聚氨酯灌浆料在复杂水环境下作为坝体灌浆堵漏材料均有适合的凝胶时间、包水性能,遇水膨胀率和干湿循环后遇水膨胀率的变化率等指标也较出色;在实际应用工程中,该材料表现出良好的可灌性和高效的堵水性能,是水工大坝堵漏治理的较优选择。As grouting and leakage blocking material for the dam, the developed high-performance polyurethane grouting material cures in a proper period and has suitable water stopping property under complex water environment. Its swelling rate with water and variation of swelling rate with water after dry-wet circulation are splendid. In practical engineering, this material demonstrates good groutability and efficient water stopping property, and it is believed to be an excellent option for leakage treatment of hydraulic dam.
