The Application Of Steel Fiber Concrete In Reinforcing (Design) The Dam Of Fu-zi-ling Reservoir

In this paper, based on analysis the problem of the dam, though analysis the old structural design of the both head arch sheeting and all crib dam, sorts of reinforcing methods were afforded, these methods was compared from the view of technique and economy, the method that was adopt is treating the minor surface and minor inside crib of the dam by jetting steel fiber concrete.in order to skid resistance, cast-in-site steel fiber concrete was filled inside the end of crib dam by pumping up, and the method of the reinforcing structure was analyzed. The method of the dam racking treatment was provided. Though the laboratory experiment and site test of the steel fiber concrete, the compression strength tensile strength, rupture strength, bond strength with the old concrete, bend toughness index and toughness factor in difference ratio of mixture and admixture were analyzed. The background information and quality assurance were provided for the reinforcing construction execution of work of the dam. After reinforced, the dam can provide the predication effectiveness and degree of safety, and the new method that apply the new material and technology was developed in An-Hui province and the reinforcing of the dam.
