... ABSTRACT: A large coal stockpiling and transhipment development at Paradip, on the Bay of Bengal, involved raising of a soft soil site using hydraulically placed dredged fill. This case history describes the investigation, design, construction, and settlement performance the stockpiling area...

... history of the site and its environs. The premise of the paper is that the conditions and geotechnical characteristics of the ground are the product ofthe geological and geomorphological history ofthe site, including past and present climatic conditions, in short, its total geological history...

...) represent the dynamic effects from the first time step, i.e. the dynamic history. Similarly for the Mth time step we obtain the matrix equation ~M-k+lJdk J (4.7) where the summation represents the complete dynamic history from the preceding (M-l) time steps. Upon examining the left-hand sides...

..., peak strength and post failure behaviour of these shale materials have been studied. INTRODUCTION Borehole instability has been a significant contributor to unproductive drilling time during the history of drilling for hydrocarbons. As a consequence, drilling costs have been unacceptably high...

... ABSTRACT: An analysis is given of a case history of the deterioration of a gallery along a long wall coal panel during the extraction of the coal. Many observations have been carried out during the winning of the panel and additional information was gathered during the winning of a second coal...

The uncertainties may also affect the extrapolation of the model to low stresses which are probably encountered around underground structures after long times. LABORATORY...

As a matter of fact, one of the few case histories of thermal spalling actually took place in the Canadian Sheild. In the following sections, the paper will give...

... The conventional triaxial shear test apparatus was incorporated into an electro-hydraulic servo loading system by which any arbitrary form of axial load history could be applied to test specimens. The irregular time histories stored in the recorder were transmitted to the actuator to produce controlled motions...
