Ground fissures, as a typical geohazard, pose potential georisks to the construction and maintenance of urban transportation infrastructure. Under influence ground segmented tunnel structure used in subway systems complicates propagation train vibrations. In this study, soil acceleration, earth pressure contact three-section under dynamic loading fissure environment were observed analyzed by physical modeling tests, effects presence activity segmentation discussed.

Numerical Analysis of Seepage Field Response Characteristics of Weathered Granite Landslides under Fluctuating Rainfall Conditions

Water, Journal Year: 2024, Volume and Issue: 16(14), P. 1996 - 1996

Published: July 14, 2024

The threat and destructiveness of landslide disasters caused by extreme rainfall are increasing. Rainfall intensity is a key factor in the mechanism rainfall-induced landslides. However, under natural conditions, highly variable. This study focuses on Fanling investigates effects varying amplitudes, durations, total amounts behavior. Three experimental groups were established, ten conditions simulated numerically to analyze seepage field response fluctuating conditions. results indicate that (1) there positive correlations between final pore pressure both amplitude duration intensity; (2) water upper slope changes significantly, initiating deformation; (3) amount most direct affecting deformation. Compared long-term stable rainfall, short-term rainstorms more likely trigger These findings enhance our understanding mechanisms providing valuable insights for disaster prevention mitigation.

For the expansion soil slope in JiangHuai area before disposal of neglect weak defects and after poor long-term stability current situation. This study investigates ability ecological protection technology to cope with destabilizing geohazard expansive slopes. Analyzing collapse reasons slopes region based on reinforcement project along highways region, combined actual engineering research, a “storage-resistance” water regulation prevention control is proposed. The feasibility sustainability discussed terms its principles influencing factors, effect verified by combining numerical simulation field test methods. Research findings suggest that effectively prevents rainwater infiltration, particularly under light rain conditions, continuous blocking capability. Under rainstorm it can prevent infiltration for about 4 h, significantly enhancing stability. Slope rate variations show no significant impact reinforced stability, maximum deformation occurring at slope’s foot rainfall. Reinforcement plans should prioritize strengthening support base. Proper selection optimization technical parameters lead more economical sustainable solutions while extending time. Field trials confirm suitability “storage blocking” where prevails. These techniques regulate moisture changes reduce risk instability.
