Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-570
.... Measurements of pipe strain, soil stress and pipe deflections obtained from the laboratory tests are reviewed, as are solutions obtained using a closed form analytical solution based on linear elasticity. Conclusions are drawn regarding which techniques are most suitable for conducting parametric studies...

..., as the sheetpile was relatively flexible it would deflect because of the lateral pressure. In the present case, the deflection was believed to be significant for a 20m deep sheet pile. Increase of the penetration of the sheetpile would not help to arrest the deflection. Some projects in the Changi area used...

.... The deflection and distortion behaviour of the continuous footings is also presented as comparative studies of cases with and without granular mattresses. INTRODUCTION Khulna City, situated in the south east of Bangladesh, is generally underlain by soft Recent swamp deposits containing layers of decomposed...

... ABSTRACT: Underground roof rock beams crossed by vertical joints, are analysed numerically. Various joint patterns and joint material compliances, are considered. Their effect, for small deflections, is related to the mechanical response of the roof rock beams; i.e. the joint contact length...

... of the laser onto the photodetector is converted to an image of cantilever deflection as it interacts with a surface. The AFM is today used for imaging most surfaces, from surfactant layers (Bhushan et al ., 1995) to electronic materials (Teuschler et al ., 1996) through to biological molecules such as DNA...

... ABSTRACT: There are relatively few reported field studies on the behaviour of laterally loaded rock socketed piles. This paper presents case studies of piles socketed in granite and sedimentary rocks that have been laterally load tested to failure. The load-deflection response, and deflection...

... and deflection in existing nearby piles, which may affect their integrity. There have been reports of severe damage to piled foundation due to soil cuts ( e.g . Finno et al , 1991; Chu, 1994), and thus it is important to develop a better understanding of the problem so that appropriate measures can be taken...

During these three periods, the roof deflection was measured underground and three-dimensional numerical simulations were conducted. 1...
