Methods for estimating structural reliability using probability ideas are well established. When the residual ultimate strength of a buried pipeline is exceeded the limit, breakage becomes imminent and the overall reliability of the pipe distribution network is reduced. This paper is concerned with estimating structural failure of underground flexible pipes due to corrosion induced excessive de...

Dysfunctions and failures of buried pipe networks, like sewer are studied in this paper from the point view structural reliability heterogeneity geotechnical conditions longitudinal direction. Combined soil spatial variability Peak Ground Acceleration (PGA) induce stresses displacements. A model has been developed within frame geostatistics a mechanical description soil–structure interaction se...

Buried pipeline leakage will affect the thermal characteristics of soil environment, leading to a poor environment. In addition, natural gas possibly produces an explosion and subsequent fire, which has fatal harm. Sustainable detection underground leaks is significant part current research. this study, method for leak buried PE pipelines based on sound source investigated. The simulation softw...

Rocks and fossils do not come with labels informing us of their age. They must be understood in light of their geologic context, and interpreted within a worldview. Unfortunately, my evolutionary colleagues are often so dominated by uniformitarian brainwashing they can't objectively understand young-Earth evidence. Nevertheless, some of the evidence is clear and open for all to see. One such cl...

This paper examines a few methods used in grounding analysis and illustrates the advantages, limitations, and the applicability of these methods. Computation results using these methods are presented and compared. The various cases modeled in this paper include grounding networks of different sizes, grounding networks with buried metallic structures such as steel pipes, and high frequency cases...
