| 摘 要： | 水电站坝基岩体发生溶蚀以后会对大坝的稳定性带来较大的影响,本文以工程实例为依托,利用三维数值分析技术,分析计算了坝基岩体不同溶蚀程度对坝体不均匀沉降的影响.结果表明:当坝基岩体强烈溶蚀、中等溶蚀、轻微溶蚀以后,坝顶处的最大位移分别达到10cm、5.5cm、4cm.坝基岩体溶蚀程度越高,坝体各处不均匀沉降的程度越严重.在...

| Abstract: | The stability of dam would reduce after rock dissolution occurs at the dam base.Taking a project for example,this paper analyzes the uneven settlement of dam at different dissolution degrees of dam base rock mass.The paper uses a three-dimensional numerical analysis.The result of calculation can show the following findings: the maximum displacement on dam top will be 10 cm if a strong dissolution occurs at dam base.The maximum displacement on dam top will be 5.5 cm if a middling dissolution occurs at dam ba... |
