Determination method of key parameters of grouting in water saturated karst-fracture
Abstract：Based on the gap structure characters in karst-pore and fracture rock mass,major effect factors of grout flowing charateristics and flowing resistance conditions in different water saturated fractures was studied.Researched and calculated the controlling functions to grout flow with different grouting parameters,figured out the key parameters in grout flowing.Gave gout flowing calculation formula in parallel fracture and effective grouting pressure calculation formula in water saturated fracture.
Keywords：karst-fracture rockgroutingcontrolling factorsflowing resistanceeffective pressure
