严寒地区住宅混凝土工程(包括大板住宅)的冬季施工,怎样做到经济简便,又能确保工程质量,是我们多年来研究的课题。住宅混凝土工程(如灌注桩、承台梁、圈梁等)的结构特点是一、表而系数较大(大于10);二、多跨连续跨距小,施工荷载逐渐增加, The winter construction of residential concrete works (including large-scale residential houses) in severe cold regions is a subject that we have studied over the years as to how to achieve economic simplicity and ensure the quality of the works. The structural features of residential concrete works (such as cast-in-place piles, platform beams, ring beams, etc.) are characterized by a large number of tables (larger than 10); second, multi-span continuous spans are small, and the construction load gradually increases.
