| EXPERIMENT ON BEHAVIOUR OF POLYPROPYLENE-FIBER-NET SHOTCRETE AND LINING |
|
|
|
|
Abstract In comparison with the traditional plain shotcrete，the tensile，flexural and permeability strength of polyropylene-fiber-net shotcrete are improved for 56.2%，92.9% and 100%，respectively. The density and quality stability of concrete are improved，the resilience loss is reduced for 10%～20%，and dust is reduced for more than 100% in the spraying. In railway and highway tunnels，polyropylene-fiber-net shotcrete has been used as primary support and permanent lining successfully. A comprehensive construction technology has been formed，and the structural strength and quality have been improved in recent years.
