1979年在亚开岱克山东部山坡上对开米开米火里溪谷的泥石流,实现了有计划的观测.建立了由许多仪器装备的一个综合观测系统.这个系统已设计出来,并在这十年中投入实践中使用.在水源地区,除水文测验外,还对山坡的地形变化进行了调查,在河道区域,该观测系统除观测泥石流的流动状态外,还经常地对溪谷处出现的地貌变化进行测量.对于研究泥石流的沉积变化过程,已获得巨大的成果.为了揭示泥石流在流动、减速和静止各时期的动态,在这整个扇形地带,用许多各种类型的光学记录仪器持久地进行工作.为了调查沉积作用的特征,在发生泥石流前后都经常地进行水准测量和极坐标测量.这年在大雨之后,发生了七次泥石流,其中的一次是发生在8月22日,它是过去十年中最大的一次泥石流.在观测到的实际情况基础上,需要对下列项目进行商讨:(a)当泥石流发生时,降雨强度与其径流之间的关系;(b)用运动波浪方法,精密的分析溪谷径流,(c)小河和溪谷的强烈的侵蚀,(d)由于泥石流而产生地面振动的强度和频率特征,(e)泥石流顶部侧面的倾角,(f)季节变化对溪谷外形的影响,(g)依靠在坝后的泥石沉积物的单个泥石流规模,(h)一个大的泥石流到达具有1—2°的倾角的缓坡,(i)由于岩屑堆积物舌央的重复的沉积物形成扇形地带的发展,(j)由于泥石流和沙流侵?
A planned observation was carried out in 1979 on the mountain slopes of the eastern part of the Yalecaike Mountain against a muddy stream of rice and rice in a firestorm valley, and a comprehensive observation system equipped with many instruments was established. This system has been designed and developed In the water source area, in addition to hydrological tests, the terrain changes of the hillsides were also investigated. In addition to observing the flow of debris flow in the riverway area, The appearance of changes in the landform measurements for the study of debris flow sedimentation process has been tremendous achievements in order to reveal the flow of debris flow in the flow, deceleration and stationary periods of dynamic throughout the sector, with many types of optical recording instruments In order to investigate the characteristics of sedimentation, leveling and polar measurements were performed frequently before and after the debris flow, and seven mudslides occurred after heavy rains this year, one of which took place on August 22, It is the largest debris flow in the last decade and based on the observed realities, the following items need to be discussed: (a) When debris flows occur, (C) the intense erosion of creek and valleys, (d) the intensity and frequency characteristics of ground vibrations resulting from the debris flow, and (c) (e) the dip at the top of the debris flow, (f) the effect of the seasonal variation on the profile of the valley, (g) the size of a single debris flow relying on debris deposits behind the dam, (h) (I) the development of fan-shaped zones due to the repeated deposition of tongue deposits at the tongue center of debris deposits, (j) the invasion of debris flowed by mudslides and sand?
