Context of the project<\/h2><\/div>The Wolf Creek Dam on the Cumberland River in southern Kentucky is nearly 2 km long and supports hydroelectric generation, flood control, navigation and recreational activities. Following discovery of regressive erosion in the underlying karsts, a contract was awarded to the Treviicos-Soletanche joint venture to rehabilitate the foundations<\/a> of the dam.<\/p>\n<\/div>Description of the project<\/h2><\/div>The project involves repairing the dam to re-establish the watertightness of the dam\/rock contact, and in particular:<\/p>\n
\n- Completion of the previous contract’s grouting<\/a> at a depth of 100m, using sonic drilling and a water hammer.<\/li>\n
- Construction of a concrete wall, between the two grouting lines, at a depth of 85m (50m through the earth dam body and 35m in rock of varying strength from 50 to 200Mpa).<\/li>\n<\/ul>\n
The wall must be very vertical, with a deviation tolerance of less than 0.15% at 85m, and a minimum thickness of 600mm.<\/p>\n<\/div>
Our solution<\/h2><\/div>To solve the erosion issue, the joint venture built a barrier wall behind a 52,000 sq. metre, 1.8 metre thick, 85 metre deep diaphragm wall. The 91,000 sq. metre barrier wall, which combines secant piles and Hydrofraise\u00ae panels, runs through the embankment and extends downwards through 50 metres of clay and 35 metres of rock.<\/p>\n
The project, which won a Deep Foundation Institute<\/a> award, was handed over in 2014 following four and a half years of work.<\/p>\n<\/div>![](\"https:\/\/www.soletanche-bachy.com\/wp-content\/uploads\/sites\/18\/2023\/08\/SB_Wolf-Creek-dam-slider-1024x436.jpg\")
