- Abstract:
- The hydraulie fracturing of high earth - rockfill dams has been widely concered, When the initialand middle diversion tunnels are plugged, the reservoir water level may rise rapidly, and" water wedging” ac.tions may be indueed. The crack in the core and different of initial impounding speed for Changhe Dam aresimulated in centrifuge modeling tests. The faster the initial impounding speed is, the rapider the differenee ofwater pressure of the core near crack increases, and the larger the maximum difference is. The ultimate initialimpounding speed of the dam is 25.5 m/d.
