Analysis to mechanism of graphitic corrosion to mining area structure and reinforcement;

Accident analysis on a cast-in-place pitched roof building and its reinforcement;

The paper analyzes the mechanism of wall cracking due to differential settlement, temperature fluctuation and frost upheaval of subsoil and puts forward precaution measures for wall cracking and reinforcement techniques to deal with walls with horizontal and vertical crevices.

Based on an engineering case,this paper presents the strengthening design of struc-tures by setting carbon fiber composites and enlarging sections in actural reinforcement projects,and suggests simplified design calculations,so as to provide references for similar projects.

Building structure reinforcing in expanding engineering;

Design and construction of applying the technology of spraying concrete to remaking and reinforcing coal - towers are of specific function.

According to construction quality issues of a concrete composite beam,through the structural analysis from two aspects of strength and stiffness of the reinforcing beam,treatment methods were put forward,highlighted the importance to eliminate the construction quality problem.

Consolidation of the Structure of Reinforced Concrete after Fire Damage;

It has practical meaning for consolidation of brick masonry.

Combined with the actual engineering examples the paper introduces the whole procedure of consolidation and maintenance for the eaves boards which have been damaged as the exfoliation of the concrete and corrosion of the reinforcing steel bars.

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.
