| 摘 要： | 通过对麻竹坪水库砌石拱坝的温度和应力观测,分析砌石拱坝产生裂缝的原因是由温度应力造成的,并据此认为砌石拱坝的温控设计和温控施工至关重要,是避免或减少砌石拱坝裂缝产生的有效手段.观测到现坝体内温度稳定应力稳定,裂缝已经闭合,对拱坝的安全运行不会产生严重后果.观测数据和分析结论可以为今后砌石拱坝的设计和施工提供参考.

| Abstract: | Causes to the cracks of masonry arch dam in Mazhuping Reservoir is analyzed based on the observations of its temperature and stress. An effective way to prevent or to reduce the cracks is temperature control design and temperature control construction. When the temperature and stress within the dam becomes stable, the cracks will be slowly closed. It provides a reference for the design and construction of masonry arch in the future. |
