MIDAS Civil在穆家沟水库鲫江河渡槽受力计算中的应用

Application of MIDAS Civil in the Force Calculation of the Crucian River Aqueduct in Mujiagou Reservoir

为准确计算分析出拱槽及排架受力情况,确保其满足施工要求,基于穆家沟水库鲫江河渡槽实际,利用MIADS Civil软件对鲫江河渡槽的拱槽的各项计算指标进行验算。通过计算,拱肋在基本组合作用(最不利工况)下和地震组合作用工况下,偏心受压验算、拱肋截面强度、截面裂缝宽度以及桩基水平强度均满足规范要求。结果表明,MIADS Civil软件可以运用有限元方法精确模拟结构的受力情况,为后续施工提供可靠依据。

In order to accurately calculate and analyze the force of the arch trough and the bent frame and ensure that it meets the construction requirements,this paper uses the MIADS Civil software to check the calculation indexes of the arch trough of the crucian river aqueduct based on the actual situation of the Mujiagou Reservoir.Through calculation,under the basic combined action(the most unfavorable working condition)and the combined seismic action,the check calculation of eccentric compression,the strength of the arch rib section,the width of the section crack,and the horizontal strength of the pile foundation all meet the requirements of the code.The results show that the MIADS Civil software can use the finite element method to accurately simulate the force of the structure and provide a reliable basis for subsequent construction.
