简介：摘要：在现代社会中，由于建筑使用功能的要求，不允许设置伸缩缝，愈发常见单一结构总体长度超过规范要求的建筑物，尤其是民用大型地下室、商业综合体以及部分多层工业厂房等。这些建筑物主要采用钢筋混凝土框架结构，而此种结构的应用预示着施工时将会用到大量混凝土。相对来说混凝土在施工时较为简便，造价也相对较低，其稳定性与凝固度都相对较强，但同时混凝土的抗拉强度相对较低，如果设计不合理或者施工措施不当则容易出现混凝土开裂的情况，从而在整体建筑上产生一条或多条裂缝，影响建筑的质量与观感，甚至会造成不同程度的安全隐患。为减少此类事件的发生，本文便根据超长混凝土结构产生裂缝的原因以及防治措施进行简单探讨，仅供参考。

简介：摘要：本文全面探讨了地下室超长混凝土结构裂缝控制的关键技术。文章首先分析了裂缝形成的原因，包括材料性质、结构应力、环境因素等，然后逐一讨论了包括配筋方法优化、原材料配合比调整、后浇带与加强带的设置，以及跳仓法施工和混凝土保温隔热等控制措施。这些措施旨在减少裂缝的形成，提高结构的稳定性和耐久性。本文旨在为工程实践提供理论指导和实际应用参考。

简介：摘要北方某地某厂房平面尺寸51.5mx207.3m，考虑该地冬季温度-30℃，夏季温度32℃，钢结构屋面温度作用明显，故对200米超长结构采用设缝处理，避免温度应力累计。建筑屋面造型要求结构双面找坡，坡度8%，屋架底有净高要求，因此屋架结构采用平底双坡平板网架结构体系。网架支座采用平板橡胶支座结构优化设计，从而释放大跨度网架温度荷载作用下的水平位移。

简介：大庆炼化公司新建职工食堂主要结构形式为超长混凝土框架结构，经合理设置混凝土膨胀加强带，采用外加剂配制补偿收缩抗裂混凝土，进行超长混凝土结构无缝施工，取得了良好效果。

简介：摘要现浇混凝土框架结构长度一般超过55m，可被定义为超长结构，结构形式为开敞式的最大长度则为35m。剪力墙结构由于刚度及约束更大，长度限制则更加严格。《《混凝土结构设计规范GB500102010》（以下简称“砼规”）中建议采用设置伸缩缝的方法来降低温度应力对于结构的影响，然而由于抗震的要求，此类伸缩缝的宽度一般在100mm以上，不但影响建筑物的美观，同时也是漏水、渗水的隐患所在。而通过对温度应力的配筋计算和加强结构的构造措施，再配合适当的施工措施。完全可以做到无需设缝的超长混凝土结构。
