Large-Scale Strength Testing Of High-Speed Railway Bridge Embankments: Effects Of Cement Treatment And Skew Under Passive Loading, Daniel Ethan Schwicht
Large-Scale Strength Testing Of High-Speed Railway Bridge Embankments: Effects Of Cement Treatment And Skew Under Passive Loading, Daniel Ethan Schwicht
Theses and Dissertations
To investigate the passive force-displacement relationships provided by a transitional zoned backfill consisting of cement treated aggregate (CTA) and compacted gravel, a series of full-scale lateral abutment load tests were performed. The transitional zoned backfill was designed to minimize differential settlement adjacent to bridge abutments for the California High Speed Rail project. Tests were performed with a 2-D or plane strain backfill geometry to simulate a wide abutment. To investigate the effect of skew angle on the passive force, lateral abutment load tests were also performed with a simulated abutment with skew angles of 30º and 45º. The peak passive …
Effect Of Inclined Loading On Passive Force-Deflection Curves And Skew Adjustment Factors, Joshua Rex Curtis
Effect Of Inclined Loading On Passive Force-Deflection Curves And Skew Adjustment Factors, Joshua Rex Curtis
Theses and Dissertations
Skewed bridges have exhibited poorer performance during lateral earthquake loading in comparison to non-skewed bridges (Apirakvorapinit et al. 2012; Elnashai et al. 2010). Results from numerical modeling by Shamsabadi et al. (2006), small-scale laboratory tests by Rollins and Jessee (2012), and several large-scale tests performed by Rollins et al. at Brigham Young University (Franke 2013; Marsh 2013; Palmer 2013; Smith 2014; Frederickson 2015) led to the proposal of a reduction curve used to determine a passive force skew reduction factor depending on abutment skew angle (Shamsabadi and Rollins 2014). In all previous tests, a uniform longitudinal load has been applied …
