兰州新区庙儿沟水库心墙堆石坝沉降计算分析OA
Calculation and Analysis of Settlement of Core Rockfill Dam of Miaoergou Reservoir in Lanzhou New District
兰州新区庙儿沟水库工程地处兰州新区,为注入式水库,库容比较大,坝体采用壤土心墙土石坝.以Midas GTS NX软件为计算工具,采用邓肯-张(E-B)材料本构模型对坝体进行施工分层模拟以及蓄水期沉降计算.通过计算分析可知,坝体在施工期以及蓄水期的沉降和应力均满足规范要求,表明坝体结构设计合理.
Miaoergou reservoir,located in Lanzhou New District,is an injection reservoir with large storage capacity.The dam body adopts loam core wall earth-rock dam.MidasGTSNX software is used as the calculation tool,and Duncan-Zhang(E-B)material constitutive model is used to simulate the construction stratification of the dam body and calculate the settlement during storage period.Through calculation and analysis,it can be seen that the settlement and stress of the dam during construction period and storage period meet the requirements of the code,indicating that the dam structure design is reasonable.
