Analysis of Different Treatment Measures for Karst Caves of Aikou Pitch Core-Walled Rock-Fill Dam Base

Article Preview

Abstract:

Karst caves are found in the bedrock of Aikou pitch core-walled rock-fill dam, of which the volumes of K6 and K5 all exceed 105m3. Due to K6 is within the stress influence range of the right abutment, it has significant effect to the right abutment compression deformation, dam stability and core stress. Three stress deformation study cases(none replacement, partial replacement, complete replacement of K6) are simulated by using 3D finite element method. The result showes that to ensure the compliance of dam deformation and avoid adverse stress occurred due to differential deformation, K6 should be replaced as completely as possible
