摘要： 对海南石梅湾沿自然山体修建酒店和别墅项目的一处滑坡进行全自动监测，研究了降雨诱导滑坡的机理。监测采用了含水量计、张力计、孔隙水压力计、测斜仪以及雨量计等一系列仪器，通过与自动数据采集仪连接实现对边坡状况的实时监控。监测周期开始于2011年旱季直至2012年雨季再次发生滑坡，主要介绍了现场滑坡监测系统的设计和安装。通过对所取得的数据的分析，认为暴雨条件下边坡含水率和基质吸力的巨大变化是诱导浅层滑坡发生的重要原因。

Abstract: A landslide occurred at the hotel and residential area constructed at along the natural slope was monitored with an automatic instrumentation system. Factors that leads to the rainfall induced landslide were investigated. The instrumentation system was consisted of soil moisture probes, tensiometers, piezometers, slope inclinometers and a rain gauge. These probes are interconnected and data acquisition was completely automatic. The monitoring program started at the dry season of 2011 till the landslide occurred in the rain season in 2012. This paper introduces the design and installation of the monitoring program. It is concluded that the significant reduction of the matrix suctions and increased moisture content in the soil due to the precipitation were the major factors that leading to the slope failure at shallow depth.
