摘　　要：混凝土大坝在高寒冬季使用过程中容易受到气温骤降、冰拔、渗漏等病害,从而影响大坝的安全运行。抗冰拔保温防渗体系可以较好地同时解决这3个问题。通过在实验室对抗冰拔保温防渗体系进行了物理性能、脱冰、耐候性等测试,并在两个高寒地区进行了超过1000 m 2的施工应用,从多年跟踪测试数据可知,抗冰拔保温防渗体系能够有效解决气温骤降导致的开裂,冰拔、渗漏三者对坝体尤其是迎水面水位变动区的破坏,保证高寒地区大坝的安全运行。In the alpine region,the concrete dam is vulnerable to temperature drop,ice pulling,leakage and other diseases in winter,which will affect the safe operation of the dam.These three problems can be solved simultaneously by the anti-ice pulling,insulation and seepage prevention system.The physical properties,deicing and weather resistance are tested on the proposed system in the laboratory,and the construction and application of more than 1000 m 2 of the system have been carried out in two alpine regions.After years of the test data tracking,it is concluded that the damage caused by sudden temperature drop,ice pulling and leakage to the dam body,especially in the water level fluctuation area of dam water face,can be effectively solved by the anti-ice pulling,insulation and seepage prevention system,which will ensure the safe operation of dams in alpine regions.
