“…In a previous study [9], the durability of the GFRP pipe did not change signi cantly under a low temperature range. However, the durability of the GFRP pipe may be decreased due to the various variables found in underground conditions that are used to predict pipe de ection in AWWA M45.…”

Long-term pressurizing of buried glass fiber-reinforced polymer (GFRP) pipe will result in the reduction of stiffness in the pipes. It leads to excessive deflections in long-term design limits. In situ tests were performed for 664 days to measure deflections of buried GFRP pipe with a large diameter of 2,400 mm. Based on the field test results, finite element analysis was conducted to determine the pipe deflections with respect to the soil conditions and buried depth as variables. Regression analysis has been conducted to determine the long-term deflection of the GFRP pipe after 50 years of construction. The long-term deflection of the GFRP pipe was less than 5 percent suggested by the existing specifications including ASTM D5365 and AWWA M45. The comparison indicates the current specifications significantly conservative to predict long-term deflection of the buried GFRP pipe.

“…Theoretical analysis and numerical simulation can well explain the response law of pipeline under blasting load, but it still requires to be verified by combining the field monitoring data. [22][23][24] In addition, the structure damage of buried pipeline in service, such as material aging, corrosion defects, and other factors are rarely considered, and ignoring the influence of these factors on the dynamic response characteristics of the pipeline is inaccurate. 25 Based on the blasting excavation project of Shenzhen Metro Line 12, a full-scale blasting field test was designed and carried out to research the dynamic response of buried concrete pipelines adjacent to blasting vibration.…”

Buried pipelines in urban area are prone to corrosion defects for many years. Ensure the safety of buried corrosion pipelines is a key concern during tunnel blasting excavation. Based on the blasting engineering along Shenzhen Metro Line 12, the field test of full‐scale concrete pipeline adjacent blasting was implemented. The dynamic response of concrete pipeline induced by blasting vibration was analyzed by using the dynamic finite element numerical simulation method, and the reliability of numerical simulation was verified by the field monitoring data. On this basis, considering the corrosion defect morphology of pipeline, the distribution characteristics of peak particle velocity and peak effective stress of concrete pipeline with different corrosion depths, corrosion widths, and corrosion lengths induced by blasting vibration were discussed. The parameter analysis method was used to research the influence of corrosion morphology parameters on the dynamic response of the pipeline, and the corrosion depth of the inner‐wall of the pipeline was defined as the main control parameter of the dynamic response. According to the failure criteria of concrete materials, the safety criterion of corroded concrete pipelines with different service years subjected to blasting vibration was established.

“…The "cyclic compression theory" was the representative theory to analyze soil-structure interaction of flexible structures. The full scale engineering test was employed by Lee et al (2015) to examine the application of large diameter GFRP sand inclusion tubes for water supply and drainage pipeline. A total of 387 days data of the radial deformation of glass steel sand tube with 16 m burial depth was collected and compared to the estimation results of Iowa formula and finite difference method.…”

In this study, the load level, soil cover height, rise-span ratio, and arch foot constraint state were utilized to explore the mechanical properties of buried arch glass fiber reinforced plastics (GFRP) structures. Through the indoor scale-down test, the stress and deformation of arched GFRP structures under different load and soil cover height were investigated. Additionally, through the three-dimensional finite element method, the influence of the rise-span ratio and the constraint state of arch foot on the mechanical properties were obtained. The results indicate the new buried composite arch structure has excellent bearing capacity for the possible traffic load. Simultaneously, the semi-elliptical arch structure was believed to outperform the semi-circular arch structure when considering the external load. Specifically, increasing the soil cover height and reducing rise-span ratio were found to achieve the load-reduction effect.
