Experimental Study on Timeliness of Pullout Force of Grouting Soil Nailing
Pullout force of grouting soil nailing is a key to support. This test revealed that limit pullout force of soil nailing increased with the time. The timeliness function was asked for by Origin software. It's the cause for many failure accidents in soil nailing support engineering. But it was often neglected in engineering design and construction.
