Abstract

Abstract: The mass concrete foundation construction techniques in the complex geological conditions are introduced through a case history of the vibration isolation foundation installation. During the construction, the treatment of adverse conditions such as, karst rock cavities and pinnacles; rock blasting; deep excavation support; dewatering and mass concrete pouring; etc. are encountered. The mass construction installation issue in the complex geological conditions is resolved through the proper selection of concrete materials, watercement ratio and the proper curing method.

Key words: Complex Geological Conditions, Mass Concrete, Treatment of Karst Cavities, Rock Blasting, Deep Excavation Support
