Prediction of tunnel deformation in squeezing grounds

Engineering Geology, 2013
In this paper, dimensionally correct empirical correlations have been developed with correlation factor of 0.94 to predict tunnel deformation for squeezing grounds. Data of 63 sections from various case histories of 14 adits/tunnels/mine roadway were included for the study.

The motion of a tracked vehicle on deformable ground

Journal of Terramechanics, 1966
Abstract The rolling resistance of a tracked vehicle has been derived by taking into consideration the total soil deformation caused by the track elements. The values obtained from a consideration of final rut depth alone are shown to be about 50 per cent too small. Results of sinkage experiments on a T-75 tractor are also discussed.

Deformation Analysis in Soft Ground Improvement

2011
This book deals with the behaviour of soft ground improved by some of the more common methods, including the installation of prefabricated vertical drains (PVDs), or the installation of soil-cement columns formed by deep mixing, or the preloading of soft ground by application of a vacuum pressure in addition to, or instead of, a surcharge loading.

Ground Deformation Induced by Vacuum Consolidation

Journal of Geotechnical and Geoenvironmental Engineering, 2005
The deformation characteristics of soil subjected to vacuum pressure are discussed and an approximate method is proposed for calculating settlement and lateral displacement of the ground induced by vacuum consolidation. Laboratory oedometer test results indicate that if the vacuum pressure alone is larger than the lateral stress required to maintain an

Ground deformations in collapsed caldera structures

Journal of Volcanology and Geothermal Research, 1993
Abstract A method is presented to analyze the effect of stress-strain discontinuities on the ground deformations generated by a pressure source. This is meant to simulate the effects due to caldera structures, likely to present fractured zones at the borders of the collapsed area.

Ground Deformation Modeling in Volcanic Areas

1996
This chapter summarizes the main methods and problems in the modeling of ground deformations in volcanic areas. The basic model is assumed as a strain source embedded within an elastic medium. In particular, the success in explaining ground deformations in several volcanic areas by the simplest model, a nucleus of isotropic strain (generally known as ...
