RISThree-Dimensional Nonlinear Numerical Analysis of Consolidation of Soft Ground Improved by Sand Columns under a Freeway Embankment in Shallow Sea: Case Study
Publisher: American Society of Civil Engineers
Abstract: The freeway embankment linking Meizhou Island with Putian City in Fujian, China, passes through a shallow-sea area. Sand columns distributed in regular triangles and sand cushions reinforced with geogrids were employed to ...
Experimental Study of Precast Segmental Bridge Box Girders with External Unbonded and Internal Bonded Posttensioning under Monotonic Vertical Loading
Publisher: American Society of Civil Engineers
Abstract: Segmental prestressed-concrete box girders (SPCBGs) with external unbonded and internal bonded posttensioning tendons have been widely used in the construction of bridge structures. These SPCBG bridges have many attractive ...
A Refined Vlasov Foundation Model and Finite-Difference Method for Computing Slope Anchor Frame Resting on Nonsingle Bearing Strata
Publisher: American Society of Civil Engineers
Abstract: The Vlasov foundation model and its variations belong to two-parameter elastic foundation beam models that can rationally reflect the displacement decrease law with increasing depth within the compressible elasticity layer. ...
Moso Bamboo Soil-Nailed Wall and Its 3D Nonlinear Numerical Analysis
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new earth-retaining structure, the moso bamboo soil-nailed wall. Moso bamboo (including branches) is employed as soil nails and piles, and used to weave bamboo strip grids (replacing rebar grids) for ...
