Research on Prediction Model of Earth-rockfill Dam Deformation Based on BP Neural Network

Renmin Zhujiang, 2020
Dam deformation is a result of the combined action of multiple loads at the same time. Itis a key technology for prediction and diagnosis of deformation by exploring the potential laws anddevelopment trends of displacement monitoring data. However, the existing normal analysis methodssuch as GNSS+ prism, and automatic monitoring system have large non ...

Three-dimensional analysis of water infiltration into the Gouhou rockfill dam using saturated-unsaturated seepage theory

, 2006
The Gouhou Dam was a concrete-faced rockfill dam built in a steep canyon that collapsed in 1993 due to internal erosion during the initial reservoir filling. In this paper, the process of water infiltration into the originally unsaturated rockfill dam is

EARTH CORE ROCKFILL DAM: INTERACTION OF WATER AND SOIL

International Journal for Computational Civil and Structural Engineering
Accuracy of results of numerical modeling of the structure stress-strain state (SSS) depends on adequacy of design scheme. At elaboration of design scheme of an embankment dam the important aspect is selection of force loads from water. Water medium may
