体外预应力加固技术的理论及设备创新

The theory and equipment innovation of external pre-stress reinforcement technology

以桥梁加固的常见方法中的体外预应力加固为例,对预应力施加方法结合梁底垫块的技术改进提出了一种不需要液压系统即可施加体外预应力的施工技法,并对该技法进行了理论探索,以提高体外预应力加固技术水平。

Taking the external pre-stress reinforcement of common method of bridge reinforcement as an example, this paper put forward a con- struetion technology could be applied externally pre-stress did not require hydraulic system to pre-stress apply method combining with beam base cushion block technology, and made theoretical exploration on this technology, in order to improve the reinforcement technology level of external pre-stress.
