Dec 1, 2022 · The design of CSG dam is based on a survey of the available sand and gravel materials and excavation materials in the vicinity of the dam site, followed by tests to determine the strength parameters of the available CSG materials, and finally the design of the dam profile to match the strength criteria provided by the dam construction materials.

Aug 15, 2024 · Accurately predicting settlement of concrete face sandy gravel dams is a crucial yet challenging task. The conventional approach of point forecasting can hardly describe the uncertainties inherent in the complex dam system.

Dec 1, 2016 · The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD). This paper summarizes the...

Nov 8, 2021 · The 247-m DaShiXia (DSX) concrete-faced sand-gravel dam (CFSGD) is currently the highest structure of its type under construction in the world. By reviewing the specific conditions of this dam and common problems that have occurred in other comparable cases, this paper analyzes the technical issues that undermine the safety of the dam.

Sep 10, 1999 · Concrete faced rockfill dams have evolved to a stage where the main elements are common, and a typical cross sections of a CFRDs with sound rockfill on bedrock and with gravel fill on alluvium are shown at left.

Dec 1, 2016 · The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD). This paper summarizes the concept and principles of the CMD based on studies and practices in projects around the world.

Mar 31, 2012 · The cement sand and gravel (CSG) dam is a new style of dam that owes the advantages both of the concrete faced rock-fill dam (CRFD) and roller compacted concrete (RCC) gravity dam, because of which it has attracted much attention of experts home and abroad.

Sep 22, 2020 · For the concrete faced gravel dam, because of its complex structure (Zhang et al. 2011; Gurbuz et al. 2016), it is necessary to analyze the stress and deformation of the dam body effectively in order to ensure its normal and safe operation (Yan 2017; Chen et al. 2017; Wan et …

Sep 18, 2015 · The concrete-face rockfill dam built on the sand and gravel foundation exhibited good performance. The staged construction scheme of the dam caused uneven deformation and stress concentration in the dam body but could improve the …

With the severe cold climate, the altitude of the dam site exceeds 3000 m and the depth of river bed cover is between 18 m and 21 m. With the maximum dam height of 121.5 m, a concrete face sandy gravel dam is adopted for water-retaining.
