Electronic Measurements in Rock and Tunnel Liner Structures
Abstract
On Project 3.2, measurements were made of transient particle velocity and displacement, relative displacement, and liner and rock strain, on 24 of the 43 tunnel liner sections used in the tunnel liner response studies (Project 3.1) on Shot Hard Hat. Of the 108 instrumentation channels installed, only about 45% of the gage channels produced useful records. Some of these records were partial, being terminated by cable breakage before completion. The records obtained show peak values satisfactorily close to the set ranges; no records were lost due to over ranging or under-ranging. No detailed interpretation of these data has been attempted on this project; they will be used primarily in conjunction with other data obtained by Project 3.1. One general conclusion drawn from these data is that the majority of the structures showed maximum loading nearer the transverse than the radial direction.
