| 摘 要： | 应用渗流场三维有限元分析方法,对密集排水孔复杂渗流水力行为进行直接精细模拟,对某地下厂房厂区洞室群围岩区三维渗流场进行了有限元求解分析,对其防渗排水系统效果进行了评估。计算表明,该防渗排水系统具有强大的排水能力,同时在其外侧的防渗帷幕也具有很强的防渗抗渗能力,在工程投资范围内该防渗排水系统能够消除绝大部分地下水对地下厂房结构安全的影响,对工程有效防渗,地下厂房的建设和维护有着重大的工程意义。

| Abstract: | By 3D finite element analysis method of seepage field,through accurately simulating the complex seepage behaviors of close drainage holes,the 3D seepage field of rock caverns area of some underground powerhouse was analyzed,then the effect of anti-seepage drainage system was evaluated.The calculations show this anti-seepage drainage system has a strong drainage capacity,and its outer anti-seepage curtain also has a great capacity of anti-permeability,within the scope of engineering investment,this anti-seepage drainage system can eliminate most of the structural safety effects caused by the underground water,for the effectiveness of project anti-seepage and security maintenance of underground powerhouse,it plays a great engineering significance. |
