Abstract
Taking a defective sluice with continuous reverse arch floor as an example, the three dimensional finite element model is established to analyze and select the reinforcement scheme, in which, the foundation, floor and pier are integrated as a whole structure and the parametric inversion analysis is used to obtain unknown deformation modulus of foundation. The influences of three reinforcement schemes of full hole enclosure, half hole enclosure and continuous three holes enclosure on internal force of sluice structure are calculated and analyzed. The research shows that the three dimensional finite element method can visually and accurately reflect stress and displacement of sluice structure in the construction process. The calculation results provide a reference for selecting economic and effective construction reinforcement scheme.关键词
