Abstract: The fluctuating pressure generated by the instantaneous starting pump of the cementing operation might easily cause formation fracture in narrow safety window formations. Accurate transient fluctuating pressure calculation ...

Abstract: The composite bucket foundation (CBF) is a cost-competitive foundation for offshore wind turbines, which can be adapted to the loading characteristics and development needs of offshore wind farms due to its special structural ...

Abstract: A three-dimensional discrete element model of an asphalt mixture is developed based on discrete element method (DEM) software to investigate the cracking mechanism of the asphalt mixture, which is validated by the results ...

Abstract: Large-aperture parabolic trough collectors (LPTCs) are recognized as one of the most promising next-generation linear-focus concentrating solar power (CSP) technologies. However, large apertures inevitably introduce higher ...

Abstract: This study investigated structural safety evaluation of in-service tunnels. Considering the factors that affect the safety of in-service tunnels, the indices and grading standards for structural safety evaluations of ...

Abstract: The accurate prediction of transient surge-swab pressure, during the tripping operation under a narrow pressure window, is an important premise to ensure the safety of tripping operation and drilling. Different rheological ...

Abstract: ontinuous eddy covariance measurements of CO2, water vapor, and heat fluxes were obtained from a maize field within an oasis in northwest China from 1 May 2008 to 30 April 2009. The experimental setup used was shown to ...
