Influence of soft rock-fill material as dam embankment with central bituminous concrete membrane

Peter TSCHERNUTTER

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 1, Pages 63-70 doi: 10.1007/s11709-010-0016-3

Abstract: relevant material parameters for a valuation of the deformation behavior of the up- and downstream damshell by means of an embankment dam of medium height.This gave rise to the necessity of adjusting the dam design of the downstream dam shoulder.Several times higher dam settlements as well as significant differential settlements between the up-and downstream dam shell were observed during construction and operation.

A Brief Review of Rock-Filled Concrete Dams and Prospects for Next-Generation Concrete Dam Construction Review

Feng Jin, Duruo Huang, Michel Lino, Hu Zhou

Engineering 2024, Volume 32, Issue 1, Pages 100-106 doi: 10.1016/j.eng.2023.09.020

Abstract:

Over the past few decades, one of the most significant advances in dam construction has been the inventionof the rock-filled concrete (RFC) dam, which is constructed by pouring high-performance selfcompactingconcrete (HSCC) to fill the voids in preplaced large rocks. The innovative use of large rocks in dam construction provides engineers with a material that Prospects for next-generation concrete dams are discussed from the perspectives of environmental
