钢筋混凝土梁在使用期间要经受外界因素的和内部因素的各种物理、化学侵蚀及影响,容易引发混凝土桥梁各类耐久性病害。而水蚀病害作为桥梁耐久性病害的一个典型代表,其长期作用产生的不利影响,会导致桥梁产生结构性病害,威胁桥梁安全。本文通过对混凝土梁式桥常见水蚀病害的描述及原因分析,明确病害产生原因,加强桥梁针对此类病害的养护管理,保证桥梁结构安全。 During the use of reinforced concrete beams to withstand external and internal factors of various physical and chemical erosion and influence, easily lead to various types of concrete bridges durability of the disease. Water erosion as a typical bridge durability disease representatives, the long-term effects of adverse effects, will lead to structural defects of the bridge, threatening the safety of the bridge. Through the description and analysis of common water erosion diseases of concrete beam bridge, this paper clarifies the cause of the disease, strengthens the bridge maintenance and management of such diseases and ensures the safety of the bridge structure.
