引起大体积混凝土裂缝的原因比较复杂,施工中应采取多种防裂措施进行防控。本文以一个大体积混凝土实体试验块试验为例,对混凝土试验块进行温度实时监测,直接观测大体积混凝土内部的温度变化过程,反映出控制大体积混凝土裂缝措施的实际效果。
The cause of mass concrete cracks is complicated, and a variety of crack prevention measures should be taken for prevention and control during construction. In this paper, a mass concrete test block as an example, real-time monitoring of concrete test block temperature, direct observation of large-volume concrete temperature changes within the process, reflecting the actual measures to control the mass concrete crack effect.
