Research on the application of compound-grouting reinforcement technology to earthquake damaged masonry structure

摘要

Houses of different structures are destroyed inordinately in Wenchuan earthquake.The weight and stiffness of multi-story masonry walls is big and they are destroyed seriously.In this paper,the earthquake damaged brick-concrete structural walls in Southwest university of science and technology are repaired and reinforced using compound-grouting reinforcement technology.By comparing the bearing capacity of the walls before and after repaired and reinforced and calculating,the result that reinforcement effect is good when adopting compound-grouting reinforcement technique to reinforce the masonry walls and the beating capacity of reinforced walls is restored and improved is got.
