二维随机裂隙岩体灌浆数值模拟

Two-dimensional numerical simulation of grouting in random fractured rock mass

在已有裂隙岩体灌浆研究的基础上,建立随机裂隙网络宾汉姆浆液的渗透模型,利用Monte-Carlo法生成岩体裂隙网络,研究宾汉姆浆液在该岩体裂隙网络内的渗透规律,以及灌浆过程中裂隙变形对灌浆的影响.研究结果表明,通过该模型可预测浆液在岩体中的渗透状态,改进灌浆参数,提高灌浆质量.

Based on the former research, a seepage model for Binghamian grouts flowing in random fracture network was developed, and the Monte-Carlo method was used to generate the fracture network. The study of the seepage law of Binghamian grouts in the fracture network and the influence of fracture deformation on grouting shows that the model may help to predict the seepage state of grouts, to adjust the grouting parameters, and to improve the quality of grouting.
