桥梁支座检查镜的开发与应用

桥梁支座脱空现象是引起梁桥铰缝破坏、梁板产生斜裂缝、单片梁受力和桥面破坏的主要原因,大大降低了桥梁使用寿命。除施工误差外,缺乏有效的检查手段是支座脱空现象普遍存在的根本原因。本文提出的桥梁支座检查镜为桥梁支座脱空现象的检查提供了有效方法。

Exploitation and Application of Bridge Bearing Inspector

Bearing connection failure in beam bridge is the main reason for damage of hinged joint,slanting crack of beam or slab, supporting load by one beam or slab and damage of bridge deck pavement,which shortens the using llfe of bridge.Lacking of inspec- tion methods is the key reason for more bearing connection failure problems except for construction error.This paper provides a bridge bearing inspector which is the effective tool for inspecting of bearing connection failure.
