Numerical Study on the Cavity-Induced Piping Failure of Embankment
Abstract—Cavities are frequently found beneath conduits on pile foundations in old embankments. Cavity reduces seepage length significantly and consequently causes piping failure of embankments. Case studies of embankment failures indicate that the relative settlement between ground and pile supported-concrete conduit was the main reason of the cavity. In this paper, an attempt to simulate the ...
متن کاملEmbankment overtopping protection systems
For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....
متن کاملHighway Embankment Construction Procedure
some heavy clay soils of the A6 and A7 types with tar emul sions and cutbacks on an experimental subgrade stabilization during the summer of 1937, we found that this type of soil stabilization presents some very different problems from those of soil-aggregate stabilization. Soil-cement stabilization, as described by Mr. Myers, also presents some interesting problems. According to its claims, t...
متن کاملSlope Failure of Embankment Dam under Extreme Flooding Conditions: Comparison of Limit Equilibrium and Continuum Models
During the spring of 2003, the downstream slope of an embankment dam began to move during an extreme flooding event. The current study was implemented to evaluate the slope stability of the embankment and as a case-study to compare the limit equilibrium and continuum modeling methods. Initially, stability analyses were performed using conservative shear strength of soils estimated from both bor...
متن کاملLiquefaction of Earth Embankment Dams
Paul C. Rizzo Associates, Inc. (RIZZO) has developed efficient computational tools to evaluate the liquefaction potential of earth embankment dams located within high risk seismic regions. Two relevant case histories are the Saluda Dam and the Santee Cooper East Dam Extension, both structures susceptible to liquefaction, and located in South Carolina. Saluda Dam presents liquefaction risks with...
