City of Vantaa considers constructing a truck parking area and a filling station on a soft clay deposit in Luhtaanmäki, Vantaa (in Finland). The aim of this study was to evaluate whether vacuum preloading with vertical drains is a feasible ground improvement method for the site. Besides in situ –tests and classification tests, overall 18 oedometer tests were carried out. Preliminary design of v...

A slope formed when there is a height difference between two points of the ground surface. Limited or ambiguous data defined in the studying of the slip surface have always been posed as a challenge to engineers and geologists; however, previous studies presented the useful strategies for resolving this challenge. In general, Multi Layer Perceptrons (MLPs) (with three input, output and hidden l...

The project of Qinghai-Tibet Railway (QTR) confronts the challenge of surface displacements resulted from seasonal freezing bulge, thawing subsidence and compression settlement. Therefore the embankment instability monitoring is essential for policy makers as well as emergency managers for its operational safety. In this study, we implemented SAR interferometry for extracting ground deformation...

Snow drifting is a typical natural disaster, and an increasing importance has been attached to its theory research and field observation for the sake of cold region engineering. Numerical simulation, as an efficient method of studying snow drifting, promises to be widely applied in this field. In this paper, the finite element method is used to simulate the wind velocity field. Selected upwind,...

Full-scale experimental case studies have shown that the induced trench construction method effectively reduces vertical earth load is exerted on culverts installed beneath high embankments. Induced are traditionally designed basis of Marston’s theory; however, various theoretical shortcomings this formulation recently come to light. In paper, a new presented. The proposed analytical model empl...

That is the daily challenge for the operators of the giant dump trucks used in surface mines. As a result, each year, an average of 20 accidents and three fatalities occur involving collisions between a piece of surface mining haulage equipment and either a smaller vehicle, a worker, or some other object. Another 21 accidents occur and three mining equipment operators are killed each year when ...

Highway construction projects are one of the most important construction projects in the world. Therefore predicting the time of these kinds of projects is important. Basically highway projects are including few activities which are repeating along the horizontal direction. One of the best methods for scheduling these types of projects is linear scheduling method. The repetitive nature of the h...

Failure of dams due to overtopping is among the most frequent forms of embankment failures. Owing to massive and wide spread damage to structures and loss of lives associated with a dam failure, the subject has drawn the attention of scientists. The study also becomes essential for damage assessment and for development of early warning system of people downstream of the embankment. The rate of ...
