混凝土在现代工程建设中占有重要地位。而在今天,混凝土的裂缝较为普遍,在桥梁工程中裂缝几乎无所不在。究其原因,对混凝土温度应力的变化注意不够是其中之一。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。
Concrete occupies an important position in the construction of modern engineering. Today, cracks in concrete are more common and cracks are almost everywhere in bridge engineering. The reason, the change of temperature and stress of concrete is not enough attention is one of them. In mass concrete, temperature stress and temperature control are of great significance. This is mainly due to two reasons. First of all, concrete often cracks in the construction, affecting the integrity and durability of the structure. Secondly, during the operation, the temperature change has a significant impact on the stress state of the structure. We are mainly encountered in the construction of the temperature cracks, so this paper only on the construction of concrete cracks in the causes and treatment measures to do a discussion.
