新村滑坡位于云南哀牢山中段东麓,为残坡积层滑坡,受地质构造作用及外界诱发因子影响明显。综合考虑滑坡的多种因素关系,在勘查工程配合下,开展地表位移、深部位移、含水率、孔隙水压力、水位、降雨量等6类参数监测,以1 h为间隔进行数据采集,建立了自动监测、自动传输、自动入库等全自动监测系统,捕捉降雨入渗导致滑坡内部相关参数的变化特征,为研究降雨-入渗-斜坡变形破坏提供基础数据支撑。根据2010年7月20日至8月2日监测时段的结果分析,该降雨过程使滑面附近含水率随降雨的影响增大了2%,水位升高1.1 m,水位升高滞后降雨1~2 d,导致①号地表位移监测点出现24 mm的局部滑动,但未引起深部位移的明显增加,该降雨条件下滑坡整体处于基本稳定状态。
The Xincun landslide is located at the eastern foot of the middle section of Ailao Mountain in Yunnan Province, and is a landslide with a residual slope. It is obviously affected by geological tectonics and external factors. Considering the relationship of various factors of landslide, under the cooperation of the exploration project, six kinds of parameters such as surface displacement, deep displacement, water cut, pore water pressure, water level and rainfall were monitored and data were collected at intervals of 1 h. Automatic monitoring, automatic transmission, automatic storage and other automatic monitoring system to capture the rainfall infiltration lead to changes in the internal parameters of the landslide characteristics of the rainfall-infiltration-slope deformation and destruction to provide the basis for data support. According to the results of monitoring period from July 20, 2010 to August 2, 2010, the rainfall increased the water content near the sliding surface by 2% with the rainfall, the water level increased by 1.1 m, the water level increased and lagged by 1 ~ 2 d, resulting in ① surface displacement monitoring points 24 mm local slips, but did not cause a significant increase in deep displacement, the rainfall conditions in the overall stability of the landslide.
