王家厂水库南涵管纵向裂缝成因分析

Analysis about Cause of Longitudinal Cracks on Conveyance Conduit of Wangjiachang Reservoir

王家厂水库南涵管在运行过程中由于出口闸门操作失误 ,在涵管顶部及两侧中部附近沿管身产生三条纵向裂缝 ,采用三维有限元对其成因进行计算分析。

Three longitudinal cracks happened on the top and mid-part of both sides of the conduit under the dam of Wangji-achang reservoir for conveyance water to south irrigation channel because the exit gate faultily operated. For the purpose of finding out the cause of formation of these cracks, the 3D finite element simulating calculation is engaged.
