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.

Inelastic Deformation of Pipelines Induced by Temporary Ground Deformations

Volume 2: Pipeline Safety Management Systems; Project Management, Design, Construction, and Environmental Issues; Strain Based Design; Risk and Reliability; Northern Offshore and Production Pipelines, 2018
This paper describes a new design method to obtain the inelastic deformation of pipelines induced by temporary ground deformations. The proposed design method consists of an elastic solution and a strain conversion procedure which was developed to predict the inelastic strain distribution by using the elastic solution and a stress-strain curve ...

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

Precipitation, Groundwater and Ground Deformation

1990
Strainmeters and tiltmeters installed on or at a shallow part under the ground surface record ground deformations caused by rainfall. Such deformations are detected to a depth of several ten meters with these instruments, and accordingly they are main noises to observations of crustal movements and/or earth tides with these instruments.

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.

Three-Dimensional Bridge-Ground Liquefaction-Induced Deformations

2021
Global response of bridges is dictated by soil-structure interaction considerations of the entire bridge-ground system. In this study the three-dimensional (3D) longitudinal response of such a bridge-ground system is numerically investigated. A realistic multi-layer soil profile is considered with interbedded liquefiable/non-liquefiable strata.

Numerical Modelling of Aseismic Ground Deformation Problem

2021
For problems involving aseismic ground deformation in seismically active areas, numerical approaches based on the finite element scheme with discontinuity have been developed. We emphasise the utility of such numerical techniques in tackling geodynamics problems.

Ground-Deformation Methods and Results

1996
A comprehensive volcano-monitoring program should include techniques to measure surface deformations in order to contribute to a complete characterization of volcanic behavior. Conventional modern geodetic techniques provide useful tools for the capture of discrete or continuous ground-deformation data. Baseline data volcano deformation observed during

Jointed Pipeline Response to Large Ground Deformation

Journal of Pipeline Systems Engineering and Practice, 2016
AbstractThe performance of segmental pipelines under large ground deformation is strongly influenced by the axial pullout and compressive load capacity of their joints, as well as by the limits on joint rotation during permanent and transient ground deformation.

Ground deformation monitoring in the UAE

2023
Σε αυτή τη διατριβή μελετήθηκαν οι παρελθούσες και οι παρούσες εδαφικές παραμορφώσεις στο ανατολικό τμήμα του Εμιράτου του Αμπου Νταμπι και στην πόλη του Αμπου Νταμπι. Η πρώτη περιοχή είναι κυρίως αγροτική όπου η εξάρτηση της από τα υπόγεια ύδατα είναι καταγεγραμμένη, ενώ η επέκταση της πόλης του Αμπου Νταμπι προς το εσωτερικό των Ηνωμένων Αραβικών ...
