摘要(Abstract)：

针对滑坡临滑预报难点问题,以建立滑坡的监测预警系统为目标,依据原有T-t模型的固定临滑判据,以西原模型为基础通过理论推导出蠕变型滑坡等速应变速率和临滑切线角的关系式,建立了通过滑坡均速阶段速率确定临滑切线角的动态评估方法,继而通过对20个典型蠕变破坏与23个未破坏滑坡监测数据验证了该方法的可靠性。在此评估方法的基础上结合当今流行的无线传感器网络、云平台技术研发了一套基于无线组网技术的滑坡智能监测预警系统。结果表明,该滑坡监测预警系统具有滑坡自动评估、无线组网、自适应Kalman滤波、变频采样控制、数据掉线重传、虚拟化存储、三维地理信息展示等技术特点。目前该系统已在川黔铁路裁缝岩滑坡取得应用,为铁路运营提供准确、可靠的监测预警信息。
