The western region of China is rich in hydropower resources and characterized by unique geological conditions. For the construction or planned high dams this region, different types cover layers are formed due to special structures, most which located seismic intensity zones. This study focuses on four site conditions: hard ground, medium–hard medium–soft weak ground. By simulating dynamic resp...

Inversion analysis is usually an efficient solution to process the monitoring data of earth-rockfill dams. However, it still difficult obtain calculation results that are consistent with due different construction statuses. To deal this situation and introduce a new improve accuracy, general method inversion based on back-propagation neural networks original step-by-step assuming parameters con...

Dams and ponds as engineering structures pose various risks during design, construction operation. Deformation in dams, slope stability problems or excessive pore pressure can cause serious damage that cannot be prevented. It is critical to position these areas correctly evaluate the potential quantitatively. In rockfill work needs done planning project phase, especially on infiltration safety....

Stress relaxation properties have a significant impact on the performance of polyvinyl chloride (PVC) geomembranes (GMBs) at peripheral joints membrane faced rockfill dam (MFRD). This paper presents fractional order viscoelastic model (FOVM) to measure stress as function time. Model parameters were obtained by best fit results from wide-width strip tensile tests conducted three rates and initia...

Infrastructures play an important role in urbanization and economic activities but are vulnerable. Due to unavailability of accurate subsurface infrastructure maps, ensuring the sustainability resilience often poorly recognized. In current paper a 3D topographical predictive model using distributed geospatial data incorporated with evolutionary gene expression programming (GEP) was developed ap...

A quantitative understanding of soil water content or soil water status is of great importance to many applications, such as landslide monitoring, rockfill dam health monitoring, precision agriculture, etc. In this paper, a feasibility study was conducted to monitor the soil water content in real time using permanent embedded piezoceramic-based transducers called smart aggregates (SAs). An acti...

The establishment of relationships between the shear wave velocity (V s ) and other geotechnical parameters rockfills under large strains (e.g., oedometer-constrained modulus, M oedo , tangent elastic E t is a significant step toward precise modeling earth structure stress–strain behavior. In this study, four specimens reconstituted from rockfill used for Romaine-2 dam construction were investi...
