摘　　要：根据华丰煤矿地表移动、斑裂发育规律,分析了地表斑裂对桥梁的影响特点以及影响的表现形式。在此基础上,根据鲁里桥的实际情况,对其采取加固保护技术措施:桥梁上部结构加固、下部结构加固、桥梁基础(钻孔灌注桩基)加固、桥梁地基(岩体浅层斑裂线)加固、加强注浆控制地表变形。同时,对鲁里桥采用常规监测和紧急监测结合的方法进行监测,尤其是加强对隐伏斑裂的探测工作。通过实施一系列控制桥梁变形技术措施,目前鲁里桥能保持正常通行。According to the ground movement and cracks development in Huafeng Mine,the characteristics and forms of cracks effecting on the bridge are analyzed in this paper.Based on the actual situation of Luli Bridge,a series of technical measures have been done,such as reinforce the superstructure and substructure of bridge,reinforce the bridge foundation and cracks in shallow stratum,and strengthen grouting.At the same time,Luli Bridge is monitored in convention mode and concentrated mode,and more attention is paid to detecting insidious cracks.With these technical measures have been implemented,the Luli Bridge is in the normal use.
