Changes in subsurface water resources might alter the surrounding ground by generating subsidence or uplift, depending on geological and hydrogeological site characteristics. Improved understanding of relationships between surface storage deformation is important for design maintenance hydraulic facilities stability. Here, we construct one longest series Interferometric Synthetic Aperture Radar...

Abstract The stability evaluation of the dams subjected to seismic excitations is really very complex as earthquake response concrete gravity dam depends upon its connection joints with foundation rock. This study presents considering welded contact and friction along dam-foundation rock interface. Friction provided using elements. Two-dimensional finite element model Oued Fodda dam, located in...

Fractured seepage is an important factor affecting the interface stability of rock mass. It is closely related to fracture properties and hydraulic conditions. In this study, the law of seepage in a single fracture surface based on modified cubic law is described, and the three-dimensional discrete element method is used to simulate the dam foundation structure of the Capulin San Pablo (Costa R...

Polymer anti-seepage walls have been widely used in the reinforcement projects of earth dams. Dam crest is always supposed to meet requirements traffic load which has significant influence on dam body and wall. In order analyze coordination characteristics deformation between polymer wall under loads, a 3D finite element model an that considers coupling effect seepage field stress was establish...

Deformation prediction is an important part of concrete dam safety monitoring. In recent years, the random forest (RF) algorithm has attracted more and attention in field monitoring because its fast speed strong generalization ability. However, performance RF easily affected by many factors, such as drift measured value displacement inappropriate setting parameters RF. To solve above problems, ...

The construction of a reasonable and reliable deformation prediction model is great practical significance for dam safety assessment risk decision-making. Traditional models are susceptible to interference from redundant features, weak generalization ability, lack interpretation. Based on this, that considers the lag effect environmental quantities proposed. first constructs new influence facto...
