摘　　要：连拱坝是挡水盖板呈拱形的一种轻型支墩坝。根据连拱坝的受力特点,为了准确计算坝体的受力情况,利用了纯拱法和有限单元法(ANSYS)分别对平桥砌石连拱坝进行了应力稳定分析。计算结果表明:该坝的应力已经不能满足设计时的安全要求;在分析比较了几种加固措施后,给出了经济有效的加固方案。Multi - arch dam is one of light buttress dams and its capping plate shows arch. In order to accuracy reactor the stress characteristics of the multi - arch dam, stress of the Pingqiao multi - arch dam are analyzed by using independent arch method and ANSYS in this paper. The calculation result indicates that the stress can not adapt the safety requirement. Eco- nomical and effective method is given by comparing several strengthening measures.
