The principle and methods for parameters design of directional demolition of a thin reinforced concrete water tower by hydraulic blasting are presented.

 Since the relatively large deformation stress force caused by over-length,temperature variation and shrink of the reinforced concrete water pond is easily to create the cracks, it is pointed out that to control the temperature differences and shrink action is the main factor for controlling the crack.

With the development of wind turbine’s trend of single machine but large capacity, and with the prestressed reinforced concrete wind-turbine tower has many advantages such as high stability, corrosion resistance, lower maintenance cost, saving steels and convenient manufacture in-site, prestressed reinforced concrete tower will have more and more wide prospect.
