混凝土在水利工程建设中占有重要地位。在大体积混凝土中,温度应力及温度控制具有十分重要的意义,这主要是体现在以下两方面。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,而经常遇到的主要是施工中的温度裂缝。本文仅对施工中混凝土裂缝的成因及其处理措施做了探讨,具体如下。
Concrete plays an important role in the construction of water conservancy projects. In mass concrete, temperature stress and temperature control are of great significance. This is mainly reflected in the following two aspects. 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 non-negligible impact on the stress state of the structure, and often encountered is the temperature crack during construction. This article only discusses the causes of concrete cracks in construction and its treatment measures, as follows.
