连续刚构桥裂缝的成因及防治分析

连续刚构桥梁因具有结构截面尺寸较大、跨径较长、施工过程复杂、工程造价高等特点,其裂缝防治工作受到广泛重视。以某连续刚构桥长期监控任务为工程背景,根据该桥梁的施工工艺和监测结果,掌握桥梁的裂缝发展形态,同时参考国内外专家对结构裂缝研究的成果,提出控制和治理连续刚构桥裂缝的有效措施。

Causes and Control of Cracks for Continuous Rigid Frame Bridge

Cracks control of continuous rigid frame bridge is taken seriously because of its large sectional di- mension, long span, complex work progress, high engineering cost, and so on. This paper grasps the development form of the bridge with its construction technology and monitoring result based on long-term monitoring of contin- uous rigid frame bridge, and puts forward effective measure on control and administer of the cracks of continuous rigid frame bridge based on research achievement of experts at home and abroad on frame cracks.
