摘　　要：为了避免地质灾害引起铁路行车事故,建立有效的铁路地质灾害监测预警系统,设计了一种山体裂缝计。通过监测山体裂缝变化,进行数据自动采集,实现当山体裂缝变化率超过警戒值时发出报警信号。该山体裂缝计在西南地区铁路地质灾害监测预警项目中得到了实际应用,取得了一定的效果,实现了自动跟踪灾害发展趋势,提前预防和减少重大事故的发生,保障行车安全,并且为铁路外的地质灾害监测提供重要的关键参数和理论支持。In order to avoid the railway traffic accidents caused by geological disasters, an effective railway geological disasters monitoring and early warning system should be established. Mountain crack gauge was a kind of automatic measurement equipment which was designed to monitor the changes of mountain cracks. The crack width of the mountain is one of the most effective criteria for the early warning of geological disasters. It was implemented automatic data acquisition, issued alarm signal when the change rate of the mountain crack exceeded the warning value. The mountain crack gauge was applied to railway geological disaster monitoring and early warning project in the southwest area, and a certain effect was achieved. The gauge could be used to track the development trend of disaster automatically, prevent and reduce the occurrence of major accidents in advance, ensure traffic safety, provide important key parameters and theoretical support for the geological disaster monitoring outside the railway system.
