| 摘要： | This research report describes the engineering formulation and corresponding software developed for the rotational response of rock-founded, toe-restrained Corps retaining walls to earthquake ground motions. The PC software CorpsWallRotate (sometimes referred to as CWRotate) was developed to perform an analysis of permanent wall rotation for each proposed retaining wall section to a user-specified earthquake acceleration time-history. A particular formulation of the permanent sliding (i.e., translational) displacement response of retaining walls is also described. The resulting engineering methodology and corresponding software are applicable to a variety of retaining walls that are buttressed at their toes by a structural feature (e.g., navigation walls retaining earth, spillway chute walls, spillway discharge channel walls, approach channel walls to outlet works structures, highway and railway relocation retaining walls, and floodwall channels). CorpsWallRotate is particularly applicable to L-walls and T-walls (cantilever retaining walls) and may also be used to predict permanent, seismically induced displacements on retaining walls with or without a toe restraint. / NOTE: Final rept. / Supplementary Notes: The original document contains color images. / Availability Note: Product reproduced from digital image.
