金龙山地区滑坡综合观测方案概述

金龙山地区滑坡综合观测方案的设计原则有:阶段性、科学性、综合性和适用性。滑坡综合观测内容含:斜坡应力变化,滑体的运动变形与滑坡的地声,地下水动态,以及影响滑坡发生发展的因素(降水等)。为此在本方案中包含10个滑坡观测项目(1987—1991年已在当地开展了8个,获取3万余个数据),对观测数据由微型计算机加以综合管理。此外对组建减灾防灾组织系统(如成立指挥部和制定群防避灾措施等)在方案中也作了考虑。

A BRIEF INTRODUCTION OF INTEGRATED OBSERVATIONAL PLANNING OF LANDSLIDE IN JINLONGSHAN REGION

The design principles of this planning are staged,scientific,composite and practical.The observational contents of landslide consist of:stress variation of slope, motion deforma tion of sliding body and ground-sound of landslide, dynamic of groundwater and the factors (precipitation,earthquake )that of landslide occurring and developing.The 10 landslide observaational courses in the planning are: 1. the stress values of sliding plane or rock surface; 2. the horizontal displacement volume of sliding body; 3. the vertical displacement volume of sliding body; 4. the shear displacement volume of sliding plane; 5. the faulted volume and width of main joints and cracks(fissurss) ;6. the gradient of sliding body;7. the .gradient of borling;8. the level,discharge and tempreture of groundwater; 9. water level of reservoir; 10. the meteorologic factors of precipitation ,etc.The observational data of landslide should be comprehensively managed by the computer. In addition,the disaster reduction and prevention organizations(command post,landslide forecast and prevention disaster measures,etc. )should be set up.
