无粘结预应力混凝土超长结构技术在福大风雨操场工程中的应用

Unbonded prestressed concrete structures in Fuzhou University Gymnasium Super-long Project

针对目前出现的越来越多的大面积工程,结合工程实例,在超长结构中采用无粘结预应力技术并结合设置后浇带及其它的综合措施对减少或者消除混凝土开裂问题是十分有效经济的。

For the present situation of the growing number of large-scale projects,combined with an engineering example,the application of unbonded prestressing technology combined with setting post poured zone,and other comprehensive measures to reduce or eliminate the problem of concrete cracking in the super-long structure is very effective and economic.
