随着我国经济快速发展的同时,工民建基础工程的建筑也日益增加,因为结构上要悬索桥锚锭和工民建基础工程承台,基础结构中设计方案一般是大几何尺寸的,并且要比一般的钢筋混凝土相比较,结构更加厚实、混凝土体积更大、工程条件更为复杂、技术施工难度要求更高,水泥水化热容易致使结构产生温度和收缩变形。因此,施工很复杂,技术要求又高,工民建基础工程大体积混凝土经常出现质量问题,一旦产生问题对于工程的正常使用及其耐久性就会有危害,甚至威胁人身和财产安全,所以研究保障大体积混凝土的结构质量是异常重要的。
With the rapid economic development in our country, the construction of basic works for civil and civil works is also on the increase. Because of the structural requirements of the anchors for suspension bridges and the foundation caps for civil construction projects, the design schemes in the basic structures are generally of large geometric dimensions Comparing with ordinary reinforced concrete, the structure is thicker, the volume of concrete is larger, the engineering conditions are more complicated, and the technical difficulty of construction is more demanding. The cement hydration heat easily causes the structure to generate temperature and shrinkage deformation. Therefore, the construction is complicated and the technical requirements are high. The mass concrete of the Gongmin Civil Engineering and Construction Foundation often has quality problems. Once the problems arise, it will be harmful to the normal use and durability of the project and may even threaten the personal and property safety. Therefore, research It is extremely important to guarantee the structural quality of mass concrete.
