This study determines dam deformation similarity indexes based on an analysis of deformation zoning features and panel data clustering theory, with comprehensive consideration to the actual deformation law of super-high arch dams and the spatial-temporal features of dam deformation. Measurement methods of these indexes are studied. Based on the established deformation similarity criteria, the p...

In order to solve the supporting problem in underground engineering with high stress, square steel confined concrete (SQCC) supporting method is adopted to enhance the control on surrounding rocks, and the control effect is remarkable. The commonly used cross section shapes of confined concrete arch are square and circular. At present, designers have no consensus on which kind is more proper. T...

Joints, which are usually located in the abutments of dams, play a vital role seismic stability evaluation arch dams. This paper presents comprehensive numerical investigation influence uplift pressure joints on response an dam, with focus interaction between dam and rock wedges. For this study, Bakhtiari having one wedge at each abutment, was chosen as case three distinct finite element models...

The report illustrates the results of the activities carried out by the European Working Group. Four subjects were selected by the Group: "Regulatory Rules and/or Normal Practice" adopted in different Countries; "Analysis of Measurement Data", referring to recent relevant studies; "Numerical Modelling" to compute uplift pressures; "Clearing Of Drainage Systems". As far as regulatory rules are c...

The system identification of concrete dams using seismic monitoring data can reveal the practical dynamic properties structures during earthquakes and provide valuable information for analysis structural response, finite element model calibration, assessment postearthquake damage. In this investigation, Pacoima arch dam were used to identify modal parameters. identified parameters dam, derived ...
