摘要
连拱坝是挡水盖板呈拱形的一种轻型支墩坝。本文根据连拱坝的受力特点,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 express 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 satisfy the safety requirement. Economical and effective method is given by comparing among several strengthening measures.
