Ultimate CO2 Storage Capacity of an Over-Pressurized 2D Aquifer Model

EUROPEC 2015, 2015
Abstract This paper examines a systematic approach to determine ultimate CO2 storage capacity of two-dimensional (2D) aquifer model owing to capillary snap-off, gas dissolution, and gas compression. In our previous paper, an application of fractional flow theory was presented to evaluate CO2 storage capacity of an aquifer because of ...

Ultimate Bending Capacity and Buckling of Pressurized 90 deg Steel Elbows

Journal of Pressure Vessel Technology, 2005
The paper examines the nonlinear elastic-plastic response of internally pressurized 90 deg pipe elbows under in-plane and out-of-plane bending. Nonlinear shell elements from a general-purpose finite element program are employed to model the inelastic response of steel elbows and the adjacent straight parts.

SVM Model Based on the Influencing Factors Evaluation and Prediction of Ultimate Bearing Capacity of Statically-Pressured Pipe Pile

Advanced Materials Research, 2011
The prediction accuracy of vertical ultimate bearing capacity of statically-pressured pipe pile is difficult to ensure with traditional methods, because it is influenced by comprehensive factors, such as pile body, soil around pile and construction conditions.

Predictive Study on Ultimate Bearing Capacity of Static Pressure Pipe Pile Based on Grey Support Vector Machine

Earth and Space 2012, 2012
The paper combines grey forecasting model and support vector machine together to predict the ultimate bearing capacity of single static pressure pipe pile based on their respective advantages. New model adopts the advantage of “accumulated generating”, which is in grey forecasting method, to deal with the sample and reduce the influence of random ...

Analysis on the ultimate bearing capacity of plastic pipe reinforced by cross-helically winding steel wires under internal pressure

Ships and Offshore Structures, 2018
ABSTRACTThis paper aims to modify the engineering-design specifications of plastic pipe reinforced by cross-helically winding steel wires (PSP), in consideration of its imperfect engineering application standard. The formula of its bursting pressure is derived on the failure criterion of steel wire.

Study on calculation methods for predicting the ultimate uplift bearing capacity of pressure-cast-in-situ pile with spray-expanded frustum (PPSF)

Pressure-cast-in-situ pile with spray-expanded frustum (PPSF) is a new type of variable cross-section pile. To clarify uplift bearing mechanism of the PPSF, a series of numerical simulations of the PPSF are conducted. Criteria for determining the shear failure modes of the rock and soil surrounding the PPSF are established based on the numerical ...
