混凝土梁式体系桥梁损伤形态与机理分析

Damage Mode and Mechanism Research for Concrete Beam Bridges

在全面调查混凝土梁式体系桥梁病害的基础上,提出材料退化与混凝土裂缝是影响混凝土桥梁耐久性和使用寿命的主要损伤形态.在系统地阐述材料损伤与混凝土开裂损伤机理的基础上,指出加强桥梁日常检查与维护是保障桥梁运营安全、延长桥梁使用寿命的主要技术手段.

Through widely investigating the damage of the concrete beam bridges, the material defect and concrete cracking are the main forms of damage that influence the durability and service life of concrete bridges. Based on researching the material defect and concrete cracking mechanism, strengthening routine inspection and maintenance is the main technical method to guarantee the safety and to prolong the service life of the bridges.
