基于三维随机裂隙网络的坝基多孔分序灌浆数值模拟
Numerical Simulation of Multi-hole Sequence Grouting of Dam Bedrock Based on Three-Dimensional Stochastic Fracture Network
摘要
Abstract
The number of joint fractures in dam bedrock is large and its distribution is wildly random.Aiming at the research status of grouting numerical simulation in fractured rock mass,the method of sequence grouting is proposed based on threedimensional stochastic fractured network grouting model coupled with multi-hole,and the numerical simulation of fractured rock mass grouting with the consideration of fracture aperture random distributions is carried out for practical engineering.The influences of grouting sequence on slurry diffusion pressure field and discharge per unit width are studied.The reliability o f the method is verified by comparing the simulation values of grouting quantity and time with actual values.关键词
