Discrete element simulation study on the stability of rock chemical method anti-seepage support system
To verify the stability of the rock chemical anti-seepage support system,the particle discrete element method based on the dis-continuous medium theory using PFC software was used to simulate the stability of three different working conditions:strong permeable stra-ta without support,strong permeable strata supported only by steel pipe mold bag concrete piles,and strong permeable strata supported by the rock chemical anti-seepage support system during the excavation process of the foundation pit.Numerical simulations were conducted from particle displacement A comparative analysis was conducted on the contact force chain and displacement vector,and it was determined that the rock chemical method anti-seepage support system has improved the anti-seepage performance of highly permeable strata and improved stability.
