基于DEM的"两段法"水库塌岸预测研究
PREDICTION OF RESERVOIR BANK SLOPE FAILURE USING DEM-SUPPORTED TWO SECTION METHOD
摘要
Abstract
In this article we expand applications of "Two Section Method"from two-dimension to three-dimension. We use the Microsoft Visual Studio where meantime ArcGIS Engine component is embedded.The software program is designed to compute the width and volume of reservoir bank slope failure.By inputting some parameters including stable slope angle,lithological boundary and flood level line,it automatically runs.Hence,the prediction of bank slope failure can be completed via simple man-machine interaction,which improves the efficiency of prediction.At the meantime,the bank slope shape can be comprised between,before and after bank failure through three-dimension visualization,which can provide more reliable support of data and decision for bank protecting project.In the process of software program,there are three ways of achieving the parameters according to the need of program. They are:(1 )Using the field survey and geotechnical test results,the parameters such as bank slope angle stabilized above and underwater,can be obtained,(2)From the geological map and high-resolution Images, lithological boundary,flood level line and low level line can be achieved,and (3)From high-resolution DEM,the terrain profile line can be drawn that acts as the terminal condition of the program.关键词
