| 摘 要： | 在拱坝设计过程中,由于缺乏坝体实际温度监测资料,温度荷载采用统一公式确定,往往与坝体的实际状态存在一定偏差。以构皮滩拱坝运行过程中的温度监测数据为基础,对拱坝坝体的温度场进行反馈分析,确定实际温度荷载,并对比分析了设计时采用的温度荷载与实际温度荷载作用下的坝体应力分布规律。研究结果表明,反馈的温度荷载能较好地反映拱坝运行期间的实际状态,设计时采用的温度荷载与实际温度荷载作用下的坝体应力接近,设计阶段采用的温度荷载合理。

Research on Feedback Analysis Method for Temperature Load of Goupitan Arch Dam |
| |
| Abstract: | In the design process of arch dam, due to the lack of actual temperature monitoring data of the dam body, the temperature load is determined by an unified formula, which is often deviated from the actual state of the dam body. Based on the temperature monitoring data during the operation of the Goupitan arch dam, this paper conducts feedback analysis on the temperature field of the arch dam body, and the actual temperature load is determined. The stress distributions of the dam body under the effect of design and actual temperature load are compared and analyzed. The results show that the feedback temperature load can well reflect the actual state during the operation of the arch dam. The temperature load used in the design is close to the stress of the dam under the actual temperature load. Therefore, the temperature load adopted at the design stage is reasonable. |
