Sprayed Layer, Anchor And Soil Physical. Shotcreting With Mesh Support Use In The Pit Learn The Nature Of Synergy

In this paper the author from the theory analyses the whollygrouted anchor and the end-bearing prestressed anchor's workingmechanism and their action in enhancing soil strength value.recommended a new idea of the partly grouted prestressed anchorwith the back anchorage.dealing with plate shotcrete mesh'sworking mechanics. recommended the theoretical feasibility ofusing the thin shell instead of the thin plate in the bracing .at thesame time,basing on engineering actually date concluding theearth pressure's distribution model. Proverbing the Anchor-shotcrete-mesh's theoretical principle so that this bracing way hasa wide application prospect.
