Method for Choosing the Optimal Resource in Back-Analysis for Multiple Material Parameters of a Dam and Its Foundation

Polynomial chaos expansion for uncertainty quantification of dam engineering problems

“…Cheng et al (2015) adopted a kernel principal component analysis 2 to eliminate the impact of environmental variables and structural health monitoring under varying conditions. Su et al (2016) proposed a criterion for optimal selection of back analysis parameters based on the indices from sensitivity analysis. The uniform design method was combined with a NN and support vector machine to build the mapping relationship between multiple material parameters and location-based structural responses.…”

A series of forecasting models for seismic evaluation of dams based on ground motion meta-features

“…Next, the complex nonlinear relationship between relative values of hydraulic components of dam displacements and mechanical parameters is established. Moreover, Su et al [7] applied a similar idea on gravity dams with the extension of a criterion for optimal selection of parameters in back analysis. In this technique, the key index of optimal selection is the parameter sensitivity.…”

Numerical Analysis and Back Calculation of Embankment Dam Using Monitoring Results (Case Study: Iran-Lurestan Rudbar)

“…From back analysis in Geotechnical projects, studying the type of stability of slopes and correction methods of instability can be mentioned [22], analyzing types of tunnel, caverns and galleries stability [19], and also the calibration of models [23], analyzing, and estimation of probability of fracture expansion and its effect on the safety of concrete dams [24], analyzing earth and rock fill dams during all stages of construction and completion of construction [25]. The use of back analysis as a suitable method for selection of foundation and loan sources [26]. Rashidi and Haeri investigated the method of back analysis performed on the Gavoshan dam in Kurdistan and obtained actual parameters at the end of construction [27].…”
