Development of Simpel Monitoring system of Rock Slope

本研究报告的结果，图像分析技术，使用超远摄的天然岩石边坡行为。这些照片是用望远镜和望远镜的物镜透镜直接聚焦拍摄的。从相机（35毫米大小）到斜坡的距离约为430米。总焦距为4500毫米。45块100×100 mm的矩形板，放置在坡面上，每隔1 m左右。此外，还利用光电测距仪对图像分析计算的位移结果进行了检验。天然岩质边坡表现为：1）从冬季到春季，岩体节理张开数毫米; 2）从夏季到冬季，岩体节理反向闭合; 3）岩体的这些行为的结果可能对应于腹地地下水位的变化。用光电测距仪测量的位移结果与图像分析的结果一致。

This study reports on the results of an image analysis technique using ultra-telephotograph of a natural rock slope behavior. The photographs were took by a object lens of telescope and conveters as direct focus method. The distance from a camera(35 mm size) to the slope is about 430 meters far. The total focal length is 4500 millimeters. 45 rectangular plates (100×100 mm) were set on the surface of slope about one meter ineteval each other. In addition, An electro-optical-distance meter was used to check the results of displacement which were calculated by the image analysis. The natural rock slope showed as following behaviors ;1) From winter season to spring one, joints of rock mass became to open a few millimeter,2) From summer to winter, these joints inversely closes.3) The results for theses behaviors of rock mass may correspond to the change of an underground water level in the backlands. The resulut of the displacement measured by an electro-optical-distance meter was in harmony with the behavior of the image analysis.
