... of such constructions is associated with a high level of effort. This paper presents a newly developed foundation method in the form of a self-drilling, double-corrosion-protected micropile. This component is expected to make a significant contribution in ensuring the durability of protective structures...

... that dam deformation is closely related to the impounding process and reservoir water level is the main influencing factor. The deformation of some monitoring points near the dam foundation are also affected by aging component. The effects of temperature are negligible in the short term. In general...

.... Executive design and construction commenced in 2013. Dam foundation excavation was completed in July 2018, dam concreting and grouting in February 2022. Impounding started in November 2022 and is scheduled for completion in 2023. At the time of paper submission (February 2023) impounding had exceeded...

... ) via the Kühtai 2 power plant. The Kühtai Dam is an earth core rockfill dam (ECRD), with a maximum height of approximately 140 m above the lowest foundation level (Boes et al. 2007). MATERIAL SOURCES FOR THE DAM For the construction of the Kühtai embankment dam a total fill volume of 6.9 million m...

... ABSTRACT: The prediction of a rock joint's peak shear strength becomes complex when its joint surfaces are not fully accessible, such as the rock foundation under an existing concrete dam. This paper presents a case study with the application of a newly developed methodology that uses...

... investigation methods and targets opened new perspectives for rock mass characterization, but also disclosed limitations to be considered for a successful application. INTRODUCTION The deformation properties of rock mass are particularly important for foundations of large civil structures. Static moduli...

... to cement alkalis. This reactivity called alkali-aggregate reaction (AAR) is a slow reaction that causes the concrete to swell. Regarding the foundation, swelling of the concrete led to the transfer of stresses to the rock foundation. The intact rock is of high resistance and the rock mass of good quality...

... rocks of claystone, siltstone and sandstone from southern alberta, are presented and evaluated in this paper. These observations indicate that foundation rock discontinuities and shear zones experience considerable deformation and concurrent long term behavior, in response to excavations and reservoir...

... Abstract Cement grouting is widely used to maintain the safety of dams by reducing the water pressure in rock foundations and by improving its quality. However, little is known about the ageing of grouted joints. Some studies have suggested that erosion and dissolution caused by water flow...

... Abstract Type and shape of large dams founded on rock depend upon the expected deformation of their foundation. Their design consequently requires the assessment of the deformability of the rock mass at large scale. Seismic refraction, laboratory tests on rock samples and empirical formulas...

... Abstract Impounding deformation of slope and foundation is significant during and post dam construction. Reservoir impoundment is accompanied with various phenomena, including material degradation, effective stress decreasing and buoyancy in rock masses. These phenomena are related with some...

... Abstract Large subhorizontal joints have been found in the foundation excavations in basalt and granite of Brazilian Dams. Some spread for hundreds of square meters showed slickensides—polished surfaces plus striations—and laminations interpreted as related to shear displacement, what...
