摘　　要：滑坡监测工作已经开展了多年,本文提出滑坡监测的内容包括基础因子、诱发因子和过程因子三部分,认为诱发因子和过程因子是滑坡监测的重点。针对降雨型滑坡监测,提出降雨-入渗-位移变形三者相结合的滑坡监测技术方法,并在河口糖厂滑坡监测工程中应用,实现了监测数据的实时自动采集、自动传输、自动入库的全自动监测系统。通过监测可知,河口糖厂滑坡降雨超过50mm达到67mm时,雨水入渗深度为7m;10d累计降雨量达到110mm时,雨水入渗深度超过7m,但未至12m;雨水由0m入渗至7m的入渗速率为0.53m.h-1,由7m至12m的入渗速率为0.29m.h-1。This paper presents our investigation on landslide monitoring over last many years.Based on the results of other studies,the paper introduces the system of landslide monitoring.It can monitor geological environments,induced factors and process factor.The induced and process factor are more important in landslide monitoring.The techniques of rain-infiltration-displacement is applied to the landslide monitoring engineering at Hekou sugar refinery factory.The automatic monitoring system can make remote data collection,data transfer,data warehousing.According to the real-time monitoring data,it is concluded that the depth of infiltration was 7 m when the daily rainfall was 67 mm.The depth was more than 7 m and less than 12 m when the 10 daily rainfall was 110 mm.The speed of infiltration was found to 0.53 m·d-1 from 0 m to 7 m and was 0.29 m·d-1 from 7 m to 12 m in depth.
