摘　　要：1987年初,齐齐哈尔嫩江公路桥面翻修。自1月14日至2月25日封闭江桥的42天中,利用江面天然冰层作长时间大流量交通运输。本文论述了冰层的承载力及其影响因素,冰道的选择和设计,交通技术措施、冰道的维护和观测结果。实践表明,只要科学地利用冰层的承载力,加强观测及维护,冰上交通是完全可能的,并可为工程的施工取得明显的技术经济效益。In Jan. and Feb. of 1987, during repairing of the highway bridge on the Nenjiang River in Qiqihaer City, ice cover was used for transport and traffic for 42 days. The maximum traffic amount was 7 000 cars / day. The bearing capacity and its affecting factors, ice road choosing and design, maintenance during its operation, traffic and transport control, and in-situ observation results are presented. It has demonstrated that traffic or working on ice cover with a certain thickness has good practice as long as reasonally utilizing the bearing capacity of natural ice cover and strengthen its observation and maitenance.
