This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...

The fly ash is a waste produced mostly from the burning of coal in thermal power station which contributes to environmental pollution. It is naturally-cementitious coal combustion by-product. Many studies have been reported in the literature on the performance evaluation of soil – fly ash system as well soil-fly ashfiber system. Although ample studies have been reported with randomly distribute...

Benford’s law predicts the frequency of the first digit of numbers met in a wide range of naturally occurring phenomena. In data sets, following Benford’s law, numbers are started with a small leading digit more often than those with a large leading digit. This law can be used as a tool for detecting fraud and abnormally in the number sets and any fabricated number sets. This can be used as an ...

holocene in southwest khuzestan is represented by a fluvio-tidal succession termed thebahmanshir series which consists of two clayey layers separated by silty sand to silt beds. this paperdescribes the geotechnical properties of the clayey layers that have wide exposure in the lowlands of thepersian gulf coast. studied layers are generally clay sized and consist of a lesser percentage of clay m...

the soltan dam on the river soltan, a branch of tine river, is located about 19 km of mateur city in the northeast of tunisia. the dam is now under study and will be constructed in 2017. the soltan dam has been designed as an earth fill dam with homogeneous materials. the dam and its associated concrete structures are mainly founded on marl, shale and shale of lower miocene age, sandstone of th...

Monitoring of the slopes of surface mines can prevent loss of life, equipment, production and possibly the loss of the mine. The effectiveness of such monitoring depends on the extent to which slopes give adequate advanced warning before failing, and on the ability of the monitoring system to detect such warning. There is considerable evidence (for example, Ding et al., 1998) to indicate that s...

Existing research has shown that visual input significantly contributes to learning, therefore, it is paramount to use visual tools to help demonstrate engineering concepts. One of these tools, digital image analysis, can help effectively communicate complex concepts to students in a simple and understandable format as a supplement to traditional lecturing, while simultaneously enabling student...
