Abstract : The geology of the Stonewall Jackson dam site and a discussion of how the engineered structures were adapted to the existing rock conditions is the purpose of this report. Stonewall Jackson dam is located in central West Virginia near the town of Weston. Geologically, it is in the Kanawha Section of the Appalachian Plateau Provience and the Pennsylvanian Age rocks are mostly sandstones and shales. The principal feature of this contract was the construction of a 620-foot long, 95-foot high concrete gravity dam with a uncontrolled spillway. The rock excavation and geologic features for each of the monolithic foundations, along with the grouting program is discussed in detail. Rock excavation was by conventional drilling and blasting. A fault zone was uncovered in the foundation and had to be treated. All grout records were computerized and a detailed discussion of the program with examples is included.
