摘要
针对拱坝老化现象及产生的各种病险危害问题,对拱坝加固培厚是一种常用方法,以某拱坝背水坡培厚加固为例,采用改进等效应力法分别计算出培厚加固前、后的坝体应力,并将计算结果与规范做了对比,结果表明该方法合理可行。
According to the aging phenomenon and all kinds of hazards of arch dam,the reinforcement on height and thickness has become a widely adopted measure.Taking a certain arch dam reinforced in its downstream side as an example,an improved equivalent stress method is used to calculate the stress of arch dam before and after the reinforcement.Compared calculation results with the specification,it shows that the proposed method is reasonable and feasible.
