裂缝对混凝土结构耐久性的影响 混凝土结构的耐久性
摘要：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。在工程中，现浇混凝土板的裂缝现象也是不可避免，要求我们在现场施工中要尽量做到科学合理，采取有效的预防措施，是能够减少裂缝现象产生的；对于施工中已经产生的裂缝，在分析其发生原因后，进行科学的处理和加固补强措施，贯彻预防为主的原则，完善设计及加强施工等方面的管理，使结构尽量不出现裂缝或尽量减少裂缝数量和宽度，使现浇混凝土楼板能够满足正常使用条件下的安全性和耐久性要求，以确保结构安全。

Abstract: the concrete in the construction of modern engineering occupies an important position in the cracks of the concrete and today more common, in bridge engineering fracture in almost is everywhere. In engineering, the cast-in-situ concrete board the cracks of the phenomenon is inevitable, requests us in the field construction will need to try to do is rational and scientific, and take effective measures, is to reduce cracks phenomenon; For the construction of the crack has generated, on the analysis of the cause, the scientific process and reinforcement to fill strong measures to implement the principle of prevention, perfect design and strengthen the construction of management, make the structure try not to crack or try to reduce the number of cracks and width, make cast-in-situ concrete floor can meet under normal use
