LEFM-based fatigue life assessment of anthropogenic CO2 pipeline under inner pressure fluctuation Qiao Jin1, a, Bing Li1,b , Quan Wen2, c 1 School of Civil Engineering, Shenyang Jianzhu University, Shenyang, China 2 Faculty of Infrastructure Engineering, Dalian University of Technology, Dalian, China agoldenfss@163.com, bbingleesy@sohu.com, c wenamd@163.com Keywords: Carbon capture and storage(CCS);Anthropogenic CO2 transportation pipeline; LEFM(linear elastic fracture mechanics); crack closure Abstract.
The following conclusions can be drawn: (1) The LEFM-based damage tolerance strategy, which is based on material imperfection, is more scientific and realistic in the fatigue analysis of metal pipelines; (2) As for a pipeline with an birth or acquired crack, inner pressure fluctuation is one of the most important factors which deeply affect fatigue durability of the pipeline; (3) The introduction of crack closure effects into structural analysis of pipeline can avoid calculation results to tend conservative and make them more conform to engineering practice.

Since 1980, steel fiber concrete has been applied in the civil engineering and produced good social ad economic effects.
<>was implemented by the Engineering Construction Standardization Association in China in May, 1995.
The implementation of specification greatly promoted the application steel fiber in the highway, airport runways, bridges, hydraulic construction, buildings, railway, municipal, military engineering and various building products and so on.
Several conferences were convened and the research of the theory and technique of fiber concrete was more systematic and thorough, which were accepted gradually by the majority of engineers and technicians and was applied in the Three Gorges and other major projects.
At present, the engineering design has been guided without detailed specifications and technical documents on the application of fiber reinforced concrete.

Bridge engineering quality must been paied attention seriously.
Engineering Purposes Status.
On the basis of relevant detection of bridge process and technical standard, the static and dynamic load test have been executed, which is compared with the structure calculation result of the bridge by Midas/Civil, so as to achieve the following purposes: First, through the determination of bridge structure under the test load of actual working state, we can judge the bearing capacity whether meets the design load requirements and provide a scientific basis for final engineering acceptance; Second, determination of bridge structure inherent vibration characteristics and dynamic response through dynamic test load , so as to evaluate the actual structure dynamic performance; Finally, by the load test of bridge, initial technical archives were established.
Conclusions Combining the engineering practice, the bridge detection static, dynamic load test, testing content and safety identification method are discussed.
