| Abstract:Slot completion with advanced support was creatively bought forward during concrete leakage prevention wall making in loose sand and pebble formation for hydropower, considering hydrogeological and geotechnical characteristics of Dam Foundation. The plan was improved after three dimension stress simulation and permeation test, and during actual construction trials. The application results were excellent. |
