Study On The Harnessing Tracking For Gully Erosion Based On Embankment Dam's Construction Technique

Gully erosion, extensively distributed and intensively developed in the upper Yangtze River Basin, is the major sediment source of the Yangtze River. However, the recent studies on soil erosion are mainly concerned on the gullies in the Loess Plateau and Black soil area in Northeast China, limited to the small scope of study, and mainly based on the Global Position System (GPS) technology to describe the process of evolution. It's urgent to establish a law to describe the development mechanism of gully erosion and harnessing technology. This paper relies on the major project of western research programs (2004BA901A02) , based on the gully erosion situation of Chongqing reservoir area, focusing on the development mechanism of gully erosion and embankment dam's construction technique, give a follow-up study of dam's construction process. It gives a systematic study of the dam's commonly used forms and characteristics and numerical simulation of the high soil-rock filled dam's settlement and stability. It proposed the economic, social, other indicators after the construction and comprehensive evaluation method in the project on the basis of the structure and function track, which is important to choose the optimal economic construction technology, construction method, and putting forward practical means of construction monitoring on the premise of guaranteeing project quality. At the same time, combining visual research we have introduced a gully reclamation technology to track system and its program implementation, and achieve the entire process of tracking where the evolution of the macro-law, effective governance, development and utilization efficiency, provide disaster-oriented development trend of the interaction of management model, a dynamic the and latest tracking operating system.Research results can be used to guide the upper area of the Yangtze River in the gully erosion control, and system integration efforts of the building, where the governance program and provide the basis for the determination of reference, but also as a dynamic geological disasters in Chongqing reservoir area part of a system of tracking network for construction Geological disasters tracking database to reveal evolution of disaster and disaster control strategies, means great theoretical significance.
