简介：摘要：随着社会经济和科技的发展，我国建筑工程行业得到了极大的提升，正是由于建筑工程行业规模的扩大使得大体积的混凝土工程变得越来越多，其中大坝、桥墩等都是日常生活中常见的大体积混凝土工程，大体积混凝土的施工由于具有一定的特殊性，在施工的过程中其温度的变化所引起的拉应力在超过混凝土本身的极限抗拉强度时就会导致裂缝和开裂的问题出现，这些问题都会给工程整质量产生影响，因此为了保障工程的质量，在超长混凝土的施工中就要对温度应力和裂缝问题进行控制。本篇文章，主要就是对超长混凝土结构温度应力分析以及裂缝进行的控制和分析。

简介：摘要：随着我国综合国力的增强及经济建设的蓬勃发展，平面尺寸超长、超大的大型公共建筑、厂房结构、商业中心等迅速涌现。超长混凝土结构如果不进行裂缝控制，当裂缝宽度大于限值或者形成贯通裂缝时，不仅影响结构的使用性能，同时对建筑的耐久性和防水性也将产生不利影响。而在以往超长混凝土结构设计与施工中，往往采用设置后浇带或跳仓施工等措施来解决混凝土收缩和环境温度引起的开裂问题，但传统的后浇带施工工序繁多，时间跨度长，给工程施工带来较大的制约。为加快施工进度，降低工程造价，确保工程质量和工期，超长混凝土结构无缝设计与施工技术的研究变得越来越重要。

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。
