摘要
Abstract
In this paper, five mass concrete blocks with size of 2.5m×2.5m×1.3m were selected to simulate five working conditions in high temperature area. Fiber bragg grating sensor was used for long-term monitoring of concrete temperature, and the temperature distribution regularities inside the concrete under different working conditions were obtained. The results show that mixing water with ice, constructing in night, changing mix proportion and layered construction can impact the temperature of concrete to varying degrees. In the end, the crack prevention measure was proposed.关键词
