摘　　要：针对西湖大学地下室对地坪混凝土防开裂施工要求高的问题,从原材料、混凝土配合比、分段分块跳仓施工、递推调仓工艺、混凝土浇筑与养护措施、真缝与假缝处理方法等方面,对混凝土地坪质量进行事前、事中、事后控制,以确保填充层混凝土不出现系统性裂缝。结果显示,所采用的技术确保了地坪填充层取得了较好的施工质量,为刚性地坪施工技术试验论证提供了经验。In view of the high requirements of the basement of West Lake University on the anti-cracking construction of floor concrete,the quality of concrete floor is controlled in advance,in the process and after the event from the aspects of raw materials,concrete mix proportion,sectioning,partitioning and sequencing construction,recursive adjustment technology,concrete pouring and curing measures,and treatment methods of true joints and false joints,so as to ensure that there are no systematic cracks in the concrete filing layer.The results show that the technology adopted ensures that the floor filling layer achieves better construction quality and provides experience for the test demonstration of stiff floorconstruction technology.
