摘要
闸室结构复杂时,简化对结构应力计算影响较大,利用ABAQUS建立模型计算结构应力可以减小简化对结果的影响。以底板结构中空的某节制闸为例,对其进行有限元仿真分析,计算水闸在正常蓄水位工况时的应力与变形。根据计算结果可知,水闸在正常蓄水位工况时的安全状况良好;闸墩支座部位的应力较大,特别是在不利工况时;地基土层软且分布不均匀,翼墙处位移较大。
When structure is complex,simplifying the structure has a great influence on calculation of the stress. In order to reduce the im-pact of the simplification,establishing three-dimensional finite element model and using ABAQUS to calculate the stress of the model. Taking a sluice with hollow floor structure as an example,it carried out the finite element simulation analysis and calculated the stress and deformation of sluice under the working conditions of the nor^nal storage level. According to the calculation results,the sluice is in good condition un-der the working condition of the nor^nal storage level. The stress on bearings is large,especially under unfavorable conditions. Due to founda-tion soil layer is soft and is in uneven distribution,displacement of the wing wall is larger.
