| 摘 要： | 介绍了特殊地层条件下井壁破裂机理的研究现状,以井壁竖直附加力学说为基础,针对底部含水层疏水排放引起的地面沉降、井壁破裂问题,建立了包括井壁在内的粘弹性数学模型;同时对3个不同的含水层的数值模拟过程做了简单介绍;最后以工程实测水位降深历时曲线与模型计算曲线相对比来说明文中所建模型是可行的.

| Abstract: | The present situation of
shaft lining fracture mechanism is discussed. On the basis of vertical additional force,
viscoelastic mathematic model of surface subsidence and shaft lining fracture causing
drainage of bottom aquiclude have been set up. Meanwhile, the process of numerical
stimulation of three aquicludes have been introduced. Finally, the comparison of duration
curve of drawdown in engineering with computation curve of model is practicable. |
