某碾压式沥青混凝土心墙坝竣工期工作性状浅析

Initial Analysis on the Working Characteristics for the Asphalt Concrete Core Dam under Time of Completion

某碾压式沥青混凝土心墙砂砾石坝,在大坝竣工后采用三维非线性有限元法模拟大坝施工过程进行了反演算,结合施工期间对大坝应力应变、温度等监测数据,对大坝竣工期工作性状进行了对照研究,浅析施工过程对大坝工作性状的影响,进一步复核大坝设计的合理性与安全性。

For a sand-gravel dam with roller compacted bituminous concrete core,after the completion of the dam,by three-dimensional nonlinear finite element method,construction process of the dam was simulated.With the monitoring data of stress-strain and temperature of the dam in construction period,working characteristics of the dam under time of completion was controlly studied.Initially analysing the effect of the construction process to the working characteristics,further rechecking the rationality and safety of the design of the dam.
