摘　　要：楼前中桥位于万年县湖云乡楼前村。在桥梁拟建地段,采用高密度电法,布设测线,进行数据收集和处理,确定采空区分布范围及深度。在此基础上对采空区影响最严重的桩位钻孔,验证了高密度电法成果,并提供采空区深度准确判定。最后根据勘查成果,提出桥桩工程建议。The Louqian middle-sized bridge is to be built in the Louqian village of Huyunxiang Township, Wannian. Survey lines were laid out at the site to collect data, which were processed to determine the scope and depth of goaf distribution. Re- suits from drilling at the Pile sites with the worst goaf verified the results of the high-density electrical survey. And, according to the surveys, proposals are made of piling engineering.
