Numerical Simulation and Performance Assessment of Seepage Control Effect on the Fractured Surrounding Rock of the Wunonglong Underground Powerhouse
Publisher: ASCE
Abstract: Seepage control is a key technical problem in large-scale underground cavern engineering, and seepage analysis plays an important role in realizing engineering optimization design and safety. The long-term seepage control ...
Multiple Nonlinear Regression Models for Predicting Deformation Behavior of Concrete-Face Rockfill Dams
Publisher: ASCE
Abstract: Deformation assessment and control are important issues in the construction of concrete face rockfill dams (CFRDs). The design and construction of CFRDs require deformation behavior that can be estimated rapidly to support ...
Nonlinear Dilatancy Seepage Model of Single Rock Fracture with Shear Broken
Publisher: American Society of Civil Engineers
Abstract: The seepage behavior of a single fracture under the coupled shear–seepage condition is important to the stability of rock mass, especially when shear broken. In this study, coupled shear–seepage tests are conducted on ...
Investigation of Irrigation Canal Seepage Losses through Use of Four Different Methods in Hetao Irrigation District, China
Publisher: American Society of Civil Engineers
Environmental Impact Assessment of Mining Activities on Groundwater: Case Study of Copper Mine in Jiangxi Province, China
Publisher: American Society of Civil Engineers
Abstract: Seepage from a tailings dam associated with a copper mine located in Ganzhou, Jiangxi Province, China, may affect surrounding groundwater quality during mine operations. A groundwater environmental impact assessment (EIA) ...
Performance Assessment of the Complex Seepage-Control System at the Lu Dila Hydropower Station in China
Publisher: American Society of Civil Engineers
Abstract: The Lu Dila hydropower station has a complex geologic structure, given that it has a larger fault scale, exhibits large dam-site orientation changes, and has a more developed fissure in the dam foundation and riverbed. The ...
Comparative and Numerical Analyses of Response of Concrete Cutoff Walls of Earthen Dams on Alluvium Foundations
Publisher: American Society of Civil Engineers
Abstract: Although a number of cutoff walls have been built in dams with alluvial foundations, the produced wall response still requires further understanding. This paper focuses on the comparative study of responses of cutoff walls ...
3D Stability Charts for Convex and Concave Slopes in Plan View with Homogeneous Soil Based on the Strength-Reduction Method
Publisher: American Society of Civil Engineers
Abstract: The analysis of slope stability problems in engineering practice requires considerable attention for the three-dimensional (3D) effect of plan curvature of the slope. This paper quantifies this effect by a dimensionless ...
New Method for Investigating Crack Development in Concrete Using an Ultrahigh-Speed Camera
Publisher: American Society of Civil Engineers
Abstract: Cracks are ubiquitous in concrete materials and can destabilize a concrete structure, regardless of size or type. This study focuses on the cracking behavior of main and branching cracks in concrete. Compression tests and ...
