摘要:
以某碾压混凝土拱坝为例,采用Fortran编制的有限元计算程序,对该碾压混凝土拱坝在施工以及初次蓄水过程中的温度场和应力场进行了仿真计算。研究了诱导缝及横缝按未灌浆、50%灌浆率和100%灌浆率处理后初次蓄水对拱坝工作性态影响,进行了对比分析,并拟定了最优化设计方案,评价其防裂效果。最后给出了相关结论和建议,可为类似工程提供一定的参考价值。
Abstract:
Taking a RCC arch dam as an example, the temperature field and stress field of the RCC arch dam during construction and initial water storage were simulated and calculated by using the finite element calculation program compiled by FORTRAN. The effect of initial water storage on the working behavior of arch dam was studied after the induced joint and transverse joint were treated with no grouting, 50% grouting rate and 100% grouting rate. A comparative analysis was made and an optimal design scheme was drawn up to evaluate its crack prevention effect. Finally, some conclusions and suggestions were given, which could provide some reference value for similar projects.
