Large-scale model test study on the water pressure resistance of construction joints of karst tunnel

Frontiers of Structural and Civil Engineering   Pages 1249-1263 doi: 10.1007/s11709-023-0974-x

Abstract: numerical calculations were adopted based on the New Yuanliangshan tunnel project to investigate the waterpressure resistance of lining construction joints in high-pressure and water-rich karst tunnels.A large-scale model test was designed and conducted, innovatively transforming the external water pressureof the lining construction joint into internal water pressure.The water pressure resistance of the lining construction joint is positively correlated with the lining

Research on Development Mechanism of Sulphate-carbonate Rocks’ Compound Karst and Engineering Impacts

Lu Yaoru,Zhang Feng´e

Strategic Study of CAE 2008, Volume 10, Issue 4,   Pages 4-10

Abstract: text-align: justify;">Sulphate rock and carbonate rock both are usually distributed together, but their karstdeve -lopments are most studied separately.It is mainly to research the compound karst developmentalbetween the two soluble rocks,which are involved in the chemical karstification and the biological karstprocesses.The karst collapsed column is a special karst hazard of the compound karst,and the karst undergroundwater quality is also discussed.
