Improving Safety at Broken Bow: Technology and Teamwork Facilitate Complex Investigation

摘要

The Tulsa District of the U.S. Army Corps of Engineers (USACE) owns and operates 38 multi-purpose projects, among them the Broken Bow Dam, which includes a diversion tunnel and low level outlet facility (LLOF). The districts comprehensive dam safety program supports USACE's nationwide dam safety program. In response to concerns regarding Broken Bow's diversion tunnel and low level output facility, the district wanted to confirm safety and stability to ensure that facility operations could continue effectively without risk to operations staff or to downstream life and property. As an initial step in the risk assessment process, Tulsa District engaged the MH+MH Joint Venture to investigate the tunnel using only non-destructive testing methods to estimate the critical geologic parameters and tunnel performance.
