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...

The fast development of wireless sensor networks and MEMS make it possible to set up today real-time wireless geotechnical monitoring. To handle interferences and noises from the output data, Kalman filter can be selected as a method to achieve a more realistic estimate of the observations. In this paper, a one-day wireless measurement using accelerometers and inclinometers was deployed on top ...

A novel parallel hybrid particle swarm optimization algorithm named hmPSO is presented. The new algorithm combines particle swarm optimization with a local search method which aims to accelerate the rate of convergence. The hybrid global optimization algorithm adjusts its searching space through the local search results. Parallelization is based on the client-server model, which is ideal for as...

Soil variability is a complex attribute that can affect geotechnical engineering design. This paper presents the initial stage of a study into the variability of soil proprieties at the Port of Navegantes, southern Brazil. This study is based on laboratory and field tests that were done as part of the Port enlargement planning. The database consisted of SPT, Vane, soil characterization, oedomet...

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...

This paper presents an overview of the evolution in structural and geotechnical design practice over the past half a decade or so in relation to how uncertainties are dealt with. For the general reader who is encountering reliability-based design (RBD) for the first time, this would provide a valuable historical perspective of our present status and important outstanding issues that remain to b...

Excellent book is always being the best friend for spending little time in your office, night time, bus, and everywhere. It will be a good way to just look, open, and read the book while in that time. As known, experience and skill don't always come with the much money to acquire them. Reading this book with the PDF reliability and statistics in geotechnical engineering will let you know more t...
