内套拱圈加固法在石拱桥加固中的应用研究

Application Study on Reinforcement Method with Inner Arch Ring in the Maintenance of Stone Arch Bridges

参照拱圈上增设拱圈叠合受力加固法新设拱圈厚度的确定方法,对拱圈下内套拱圈厚度的确定提出设想,对拱圈安全厚度提出建议和确定方法。通过对烟台市界河石拱桥的损伤病理诊断,提出相应可行的加固方案,并将其应用于界河石拱桥的加固中,最后对方案实施的保证措施及取得效果做了简要说明。

According to the method of determining the safe thickness of arch ring which is reintorced by adding a new arch ring,this paper proposes a method for determining the thickness of inner arch ring under the arch bridge, By researching the damage mechanism of Jiehe Stone Arch Bridge,the feasible reinforcement scheme is put forward and applied in the reinforcement of Jiehe Stone Arch Bridge, Finally, the ensuring measures of realizing the project and its effect are briefly illuminated,
