Abstract: During the construction of channel regulation project in the middle and lower Yangtze river, plentiful stone materials are quarried through blasting, which leads to ecological destruction of stone materials source area. In view of the situation and the demand of reducing stone materials during construction of channel regulation projects, we present a new technique for channel regulation project, namely pile net-sand pillow dam(PNSPD).We propose the material structure and construction process of the new technique. On the basis of analyzing waterlogging damage mechanism of PNSPD, we put forward some countermeasures. Based on the analysis of several features, including durability, integrity, adaptability and material availability, we conclude that technical characteristics of PNSPD can meet the requirements of channel regulation project. Furthermore, as for architecture comprehensive cost for the same type and equal efficiency, PNSPD is an economical scheme in comparison with other schemes. Finally, the new technique of PNSPD is feasible for channel regulation project, with ecological, economic and social advantages for further application.

Key words: pile net-sand pillow dam, channel regulation, material structure, construction technique, technical economy
