Embankment Dam Design with Dispersive Soil: Solutions and Challenges

نویسندگان

چکیده

The configuration and safety factor of rockfill dams design depend on materials used in construction the dam. In some regions, available for using as impermeable element dam body are dispersive it is inevitable to consider dispersivity material construction. Internal erosion through cracks or other openings embankment most concern soils. authors have designed an by soil East Africa after finalizing based required tests. foundation borrow areas consisted effective measures has been considered safely deal with according recommendation codes. selected solution was combination chimney filter, filter drain, selective placement considering specification project. More precautions addition general incorporated into criteria due placing project high hazard category. local instability contact zones concerns designers bilinear parameters stability analysis base case. A drainage layer added half length blanket feature determined nonlinear static dynamic body. This paper presents that were taken account dealing order ensure design.

Forecasting embankment dam behaviour with artificial intelligence

Forecasting dam behaviour is of paramount importance to avoid collapses. It consists of detecting and controlling deterioration mechanisms. This paper sets out to propose a multi model methodology to model complex dynamic systems, such as dams. It defines three models based on expert knowledge: a structural model, a functional model and a behavioural model. They are developed from the stories o...

Embankment dam spillways and energy dissipators

For the last fifty years, the design floods of a number of embankment dams were re-evaluated and the revised spillway outflows are often larger than the original design discharges. Several embankment overtopping protection systems were developed for earthfill structures, and the applications range from river dykes to tsunami protections including embankment dams. Well-known designs include timb...

Seismic Behavior of Zoned Core Embankment Dam

The aim of this investigation is to study the dynamic behavior of a zoned core earth-fill dam. Due to lack of suitable clay materials, the Mamloo dam is designed as zoned core that is composed of three vertical zones including central lean clay (CL) core and two sides clayey gravel (GC) layers. Seismic behavior of dam was analyzed in two cases including homogenous clayey core and zoned core by ...

Energy Dissipation and Residual Energy on Embankment Dam Stepped Spillways

Stepped spillways are designed to increase the rate of energy dissipation on the chute and to reduce the size of the downstream energy dissipator. It is essential to predict accurately the turbulent dissipation above the steps for large discharges per unit width corresponding to the skimming flow regime. New measurements were conducted in a large facility with a channel slope of 21.8o and a ste...

Simple Design Criterion for Residual Energy on Embankment Dam Stepped Spillways

The stepped spillway design is associated with significant flow resistance and associated energy dissipation on the steps, yielding smaller, more economical downstream dissipation structures. A number of design guidelines were developed for steep stepped spillways typical of concrete gravity dams. The focus of this study is on embankment stepped spillways. A large set of air-water flow data is ...
