The interaction among the dam body, dam foundation and dam basin under the collaborative effect of multiple complicated external factors can significantly influence dam deformation. Based on the analysis of the super-high arch dam structural system characteristics, a model for calculating and analysing the dam-body foundation basin was established. The deformation modulus of the dam basin and the comprehensive deformation modulus were inversely calculated. By extensively considering the effect of a complicated load on the super-high arch dam structural system, the distribution features and variation law of dam deformation under different overloading conditions were studied with the overloading approach. Moreover, the actual deformation features of the super-high arch dam structure were analysed based on a super-high arch dam engineering project. (C) 2016 Elsevier GmbH. All rights reserved.
