公(铁)路下伏空洞型采空区的稳定性直接影响到整个线路的安全,而桥基下伏采空区的稳定更为关键,通过对桥基与路基的不同受力状态和变形后对线路运营的影响以及修复周期进行比对,对确定桥基下伏采空区的治理范围做了详细分析,注浆充填技术对桥基下伏采空区的治理效果与类比,为处理桥基下伏采空区的治理设计提供科学、合理的依据。
The stability of the gob of underground cavity under the public railway directly affects the safety of the whole railway line. The stability of the gob area under the bridge foundation is more critical. Through the different stress state and deformation of the bridge foundation and roadbed, After the operation of the line and the repair cycle for comparison, to determine the scope of governance under the gob of goaf bridge made a detailed analysis, grouting filling technology to the gondola under the bridge gutter effect and analogy for the treatment Bridge under the gob of governance design to provide a scientific and reasonable basis.
