It should be pay more attention to the reinforcement of reinforced concrete structure to improve the component s intension,stability,stiffness and durability.

So some reinforcement treatment is necessary to improve its quality.

It has achieved a good effect of reinforcement by underwater concrete pouring on the base slab of water cushion pool,which is taken as an example for underwater reinforcement.

Based on the test of the reinforced concrete slabs strengthened with continuous carbon fiber sheet(CFS),the effectiveness of the new method by using the CFS on repairing&strengthening reinforced concrete slabs was studied.

As FRP compound material has a series of advantages such as higher strength/weight ratio,higher rigidity/weight ratio,lower expansion ratio,anisotropy,lightness,erosion resistance, no magnetism, better fatigue resistance and durability, it can be widely used in bridge construction,fiber concrete,strengthening material,continuous fiber reinforcement,geo-technical and building engineering.

Empirical mode decomposition for dam rehabilitation effect evaluation

In order to analyze the behavior of uplift pressure of RCC dam before and after rehabilitation,the observed data are firstly analyzed qualitatively.

According to the horizontal displacement data in the period of the rehabilitation of the Shuidong dam,the influence of various factors on the deformation behavior of the Shuidong dam is analyzed by space-time analysis and a deterministic model based on the finite element method.
