| 摘 要： | 为提高混凝土坝的施工速度，可以采用厚浇筑层和短间歇期的快速施工方法。基于中国西南某大型碾压混凝土重力坝的快速施工过程，根据其施工期和初运行期的实测应变，采用变形法计算了混凝土应力，成果较好地反映了快速施工条件下混凝土坝施工期和初运行期的应力发展过程，对类似工程的施工有一定的参考价值。

| Abstract: | In order to improve the construction speed of a concrete dam, a method of fast construction using thick pouring layers and short layer intervals was used. Based on the construction process of an RCC gravity dam located in Southwest China, the concrete stress was calculated with the deformation method according to the measured strain during the construction and initial running periods. The results accurately reflect the stress development under the condition of fast construction during the construction and initial running periods, providing valuable references for similar engineering construction projects. |
