| 摘 要： | 对河北省唐山市某竖井工程施工中井壁漂浮下沉过程中任意断面的环向应变进行了弹性力学分析与有限元数值分析,通过将计算结果与实测数据进行对比,二者均与实测数据吻合较好,弹性力学解答、有限元数值分析结果与实测数据均表明环向应变与下沉深度几乎呈线性关系.有限元数值分析结果和实测数据表明,在此施工阶段中环向应变大于竖向应变. |
| 关 键 词： | 井壁 弹性力学 应变 |

| Abstract: | For one vertical shaft in Tangshan city,Hebei province,elasticity analysis and finite element numerical analysis were made for circumferential strain of any cross section of shaft strain during float sinking,both the elasticity analysis and finite element numerical analysis were in good agreement with the measured data.All the results of the elasticity analysis and finite element numerical analysis and the measured data indicated it was almost linear relationship between circumferential strain and sinking depth.Both the results of the elasticity analysis and finite element numerical analysis indicated circumferential strain was larger than vertical strain during float sinking. |
| Keywords: | shaft lining elasticity strain |
