摘　　要：冬季是工程质量事故的多发期，尤其以混凝土工程居多，由于其特殊性，我们应该总结一些冬施的经验、措施以得到一种合适、有效的保证混凝土质量的方法。新疆属干旱、半干旱气候，早晚温差大，特别是严寒地区。在-20℃以下进行混凝土施工，只要施工方案及措施完善、严谨，冬施的混凝土质量就可以得到保证。Winter is the frequently-occurring stage of engineering quality accident, the majority to concrete engineering, owing to its particularity, we should summarize some experiences and measures of winter construction to obtain a suitable and effective method of guaranteeing concrete quality. The cilmate of Xinjiang belongs to drought and semi arid, temperature difference in morning and evening is great, especially in frore region. Carrying out concrete construction below minus 20 degree centigrade, the concrete quality which in winter construction can be guaranteed as long as the construction scheme and measures be perfect and rigorous.
