THE STUDY ON THERMAL STRESS AND TEMPERATURE CRACK OF UNDERGROUND MASS CONCRETE
-
摘要: 大体积混凝土的温度变化导致混凝土产生裂缝,是混凝土工程施工非常棘手的问题,对此人们进行了大量的研究,在施工阶段的温度控制和限制产生裂缝方面也取得了一些进展。结合深港西部通道侧接线隧道工程的实际情况,研究分析工程施工过程中产生的温度裂缝,并提出相应的防止措施,取得了很好的效果。Abstract: The mass concrete cracking that attributed to temperature change is a very intractability problem in construction,many studies were made,and some progress in temperature control and crack restriction was made.It was investigated the construction process of the Shenzhen side-connection item of Shenzhen-Hong Kong West Channel Project,and analyzed the cause for the temperature crack,put forward some relevant control measures,it came out a very good result in the project.
