“…The threat posed by pipeline failures is the potential security disturbance caused by the pipeline. The most serious impact is the leakage of flammable fluids or gas, which not only disrupts the operation of the railway and the pipeline itself, but also damages the environment and potentially leads to explosions, fires, or other accidents, which threaten the safety and economic losses [19].…”

The presence of pipes beneath railway lines poses potential risks and hazards to railway operations. Identification of the risks arising from pipes located under railway lines is necessary for evaluation and preparation of strategic measures to reduce the level of risk. Risks to be aware of include pipe deformation, corrosion, design and installation errors, and operating errors. To ensure safety, pipe monitoring and inspection must be conducted regularly. Pipe inspection also needs to consider geotechnical elements to ensure that railway infrastructure remains safe for operation. This paper reviews several published studies and standards related to the safety of pipelines under the railways and summarizes the potential failures of pipelines located beneath railway tracks, various aspect of pipelines and railway safety, and the standards that can be used as references in designing pipelines buried beneath railway tracks

“…In general, buckling is the main cause of pipeline deformation, and failure may lead to oil and gas leakage, fire and explosion to facility shut down. It will bring huge losses in the business (loss of product and facility), environmental impact (pollution), safety (injury to fatality) and company reputation [6], In addition, accidental loads such as landslides may cause the failure of the buried pipeline [7] or pipeline subjected to reverse fault movement [8,…”

In the oil and gas industry, the pipeline is the main mode to transport the product and can be applied for long-distance transportation; hence some pipe segments may be buried underground. Buckling as the main cause of pipeline deformation and failure is often found at the in-service buried pipeline during inspection activity. Changes in laying conditions such as design and operational parameters, human activity and geological movement can affect the redistribution of deformation that may lead to pipe buckling. This paper presents a methodology that integrates inspection results and finite element analysis for the distorted wall of the pipeline. Inspection reported anomaly cases of wall distorted at buried gas pipeline, and the result will be used to do stress analysis using finite element analysis. Three different conditions within the different treatment of bedding conditions were assessed: pipe buried on uncompacted soil, pipe buried with rock bedding, and pipe buried in compacted soil. The result shows that the deteriorated pipe can be considered acceptable when buried in compacted soil. This condition may be used for further action and consideration, such as a mitigation strategy to maintain the safety and integrity of the deteriorated pipe.

Keywordsunderground structures reinforced concrete (RC) coupling calculation sensitivity analysis top plate deflection durabilityThe coupling effect of mechanical and environmental loads is the main cause of deterioration in the performance of reinforced concrete (RC) structures. However, most studies on the durability of RC structures have focused only on mechanical or environmental loads. As a result, it is difficult to fully capture the effects of dry shrinkage and creep caused by temperature and humidity changes within the structure, as well as their impact on the overall deformation of the structure. To address this gap, this paper presents a numerical simulation of underground culvert projects using the durability concrete model-complex three-dimensional (DuCOM-COM3D) analysis software. The results of the simulation demonstrate that this approach offers a more precise characterization of the porosity, temperature, and humidity inside the concrete, resulting in improved accuracy in predicting the longterm deflection, crack width, and other macro-mechanical indices of the structure. Despite these advantages, some discrepancies were observed between the calculated and measured long-term deflection values. Additionally, a limit analysis was conducted to investigate the potential causes of the large deformation observed in the measurements. Overall, the results contribute to a better understanding of the complex mechanical and environmental loads affecting RC structures and provide a methodology for accurately simulating their long-term behavior.
