在大体积混凝土中,温度应力及温度控制具有重要意义。这主要是由于两方面的原因。首先,在施工中混凝土常常出现温度裂缝,影响到结构的整体性和耐久性。其次,在运转过程中,温度变化对结构的应力状态具有显著的不容忽视的影响。我们遇到的主要是施工中的温度裂缝,因此本文仅对施工中混凝土裂缝的成因和处理措施做一探讨。
In mass concrete, temperature stress and temperature control are of great significance. This is mainly due to two reasons. First of all, concrete cracks often occur during construction, affecting the structural integrity and durability. Secondly, during the operation process, the temperature change has a significant influence on the stress state of the structure. We are mainly dealing with temperature cracks during construction. Therefore, this article only discusses the cause of concrete cracks in construction and the treatment measures.
