摘要
为了在试验室人工模拟环境下进行混凝土早期特性、裂缝控制及耐久性的试验 ,需对混凝土结构环境模拟试验室技术进行研究。分析了环境模拟技术在诸多领域的成功应用 ,认为建设混凝土环境试验室是可行的。通过研究混凝土结构的环境模拟、试验设计、耦合环境的实现以及特种设备仪器的应用等关键技术 ,提出大型多功能自动控制混凝土环境试验室的建设方案 ,合理确定试验室的布局、功能、技术性能指标 ,并探讨了人工气候环境试验室设备、仪器的优化配置 ,为下一步混凝土耐久性、裂缝控制的环境试验研究奠定了基础。
In order to study durability, crack controlling of concrete structu res and characteristics of concrete at early age in simulated environment, envir onmental simulation test technology is discussed. This paper describes the succe ssful applications of environmental simulation technique in some fields. The key techniques of environmental test of concrete structures are analyzed. The basic scheme is put forward to construct artificial climatic environmental laboratory with autocontrol and multifunction. Then the layout, function and performance o f the lab is determined suitably. Finally, the equipments and instruments of the lab are discussed. Based on the research, environmental test of concrete durabil ity and crack controlling will be better performed in the future.
