ANALYSIS AND EVALUATION ON HYDROFRACTURE FAILURE IN AN ASPHALT CONCRETE CORE ROCK-FILL DAM: A MAOPINGXI DAM CASE

摘要：

Whether hydrofracture failure is likely to occur in an asphalt concrete core rock-fill dam or not is one of hotspot problems widely concerned by the engineering community. In this paper, the authors adopt effective stress method to analyze the stress deformation in the core wall of Maopingxi dam and evaluate the hydrofracture problem in dams core wall in the light of evaluation criteria that minor principal stress in the core wall is no less than relevant water pressure. Calculation results show that there is little possibility of hydrofracture failure in asphalt concrete core wall of the Maopingxi dam.
