| 摘 要： | 深矿钻孔帷幕灌浆受到钻孔的垂直度、钻孔灌浆压力和扩散半径等因素的影响,使得灌浆的技术难度加大,直接影响帷幕的形态及防渗效果。采用基于UDEC离散单元程序的数值模拟方法,对深孔帷幕灌浆压力的扩散分布及浆液的流动扩散形态进行模拟,可以为深孔帷幕注浆工程设计和施工提供参考和指导。

| Abstract: | Influenced by the facts of verticality of the borehole,grouting pressure and diffusion radius,technical difficulty is increased in grouting,which directly influences the curtain shape and seepage control effect.Based on the numerical simulation method of Universal Distinct Element Code,pressure distribution and grout diffusion in deep hole are simulated,which can give reference and guidance to the design and construction for curtain grouting. |
