Stress on reinforcing ribs and concrete strain from in-situ measurement during shaft-sinking by freezing process
Abstract
Artifical freezing process and reinforced concrete sandwich linings are applied in shaft sinking at Eastern Air Shaft of Panji Colliery No.l and at Western Air Shaft of Panji Colliery No.2 in Panji Coal District with highly water-bearing Quaternary overburdens 200–400 metres in thickness, composed of silt sand, fine-grained sand, moderately coarse sand, sand clay and effervescing clay. Vibrating wire strain gauges, vibrating wire stress gauges and temperature gauges are embedded for in-situ measurement of reinforcing-rib stress and concrete strain. In this paper some results of the in-situ measurement are described.
