Application of 3S technology to the planning and designing of taking sites of soil and waste for the road construction project;

The ecological environment at the spoil(disposal) area covering permanently along the ZhangChong Section was evaluated scientifically,with presentation of reasonable suggestions for ecological restoration in the light of the geographic location,the environment,the climate and the vegetation growth.

With large quantity of waste soil and residue piled up in the course of river and ditch way, water and soil loss both remarkably rose.

<Abstrcat>The authors summarized the reason of waste caused by highway construction in Jiangxi Province and analyzed waste soil and residue prevention and control technologies which composed by field choice of waste soil and residue,drainage engineering, slope protection engineering and vegetation rehabilitation.

Aiming at the problem of comprehensive administration of Taian hydroenergy storage station, the research on techniques of comprehensive administration of abandoned dreg site was conducted according to the principle of soil erosion prevention and control, view ecology and environmental ecology in construction project.

The scheme of choosing abandoned dreg site of Taian hydroenergy storage station involved in a number of factors, such as uncertain factors, quantitative indexes, the sureness of the scheme is fuzzy.

Research on the measures to conserve soil water in the dry-hot valley areas is conducted in order to realize the vegetation restoration of abandoned dreg site of hydropower station.

The paper introduces the author\'s work experience in such problems as how to do earthwork balance well,how to fix soil borrow and disposal area and how to define areas for land acquisition,providing reference for hydraulic engineering and especially for the hydraulic project that relates to a large amount of earthwork to do earthwork balance and land acquisition.
