<p>An experimental testing program was undertaken to investigate failure mechanisms induced by the active movement of a deep rectangular trapdoor underlying a granular soil. Reduced-scale models were tested under normal gravity as well as under an increased ...

The aim of this paper is to introduce a robust methodology for the analytical calculation of strains in flexible buried pipelines due to surface point-source blasts.

Buried pipelines essentially involve problems of soil-structure interaction that include several complex factors such as geometry, material properties, and boundary conditions. Complete, comprehensive and lengthy numerical analyses using the finite element ...

Existing analytical methods for the stress analysis of buried steel pipelines at crossings with active strike-slip faults depend on a number of simplifications, which limit their applicability and may even lead to non-conservative results. The analytical methodology ...

In this paper a 3-D thin shell strain analysis has been presented, regarding long cylindrical underground structures (buried pipelines and tunnels) subjected to seismic shear (S) wave excitation.

<p>A two-year project has been funded at Cornell University and Rensselaer Polytechnic Institute (RPI) as part of Phase 2 of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) of the National Science Foundation. This project will ...

This paper discusses the stability of underground pipelines with preformed vertical bends buried in sandy soil. More specifically, the minimum cover height required to prevent the pipe from bowing under the action of forces due to temperature change and internal ...

A predictive process for determining the stresses occuring in a pipeline djacent to deep braced excavations is presented. The method can be used to establish rational criteria for determining allowable maximum values for excavation induced ground movement ...
