Performance Of The Grout Curtain At The Kentucky River Lock And Dam No. 8, Robert C. Hatton
Performance Of The Grout Curtain At The Kentucky River Lock And Dam No. 8, Robert C. Hatton
Theses and Dissertations--Civil Engineering
Karst bedrock conditions and deterioration of the lock and dam structures have resulted in significant leakage through, underneath, and around Lock and Dam No. 8 on the Kentucky River. During severe droughts, the water surface in Pool No. 8 has been observed to drop below the crest of the dam, resulting in water supply shortages and water quality issues for surrounding communities reliant on the pool. Presently, the primary purpose of Lock and Dam No. 8 is water supply. Pool No. 8 is currently where the cities of Nicholasville (Jessamine County, KY) and Lancaster (Garrard County, KY) draw their water. …

Quantifiying The Effectiveness Of A Grout Curtain Using A Laboratory-Scale Physical Model, Elliot N. Magoto
Theses and Dissertations--Civil Engineering
In the past decade, the grouting industry has made significant technological advancements in real-time monitoring of flow rate and pressure of pumped grout, stable grout mix design, and with grout curtain concepts dealing with placement and orientation. While these practices have resulted in improved construction practices in the grouting industry, current design guidelines for grout curtains are still predominately based on qualitative measures such as engineering judgment and experience or are based on proprietary methods. This research focused on the development of quantitative guidelines to evaluate the effectiveness of a grout curtain in porous media using piezometric and hydraulic flow …
