| 摘要 |
The invention is a support structure (150) for a railed-vehicle (54) that includes individual, unassembled components sized for easy transport. In one embodiment, the support structure (150) includes curved columns (160) integrally-formed with a base (162), the columns imparting a curved, Y- shap ed configuration to the support structure (150). The components may be prefabricated with known materials and methods and transported to an installation site for assembly. The support structure (150) is preferably sized to support one or two vehicle guideways (152). The support structure (150) may include a pile foundation (56b) for improved support during seismi c activity and to facilitate installation on existing streets and sidewalks without covering or interfering with underground plumbing or utilities. Preferably, multiple sections of the guideway (152) are rigidly secured together through expansion joints to define a continuous guideway (152) such that loads on the guideway are distributed over multiple columns (160).</SDO AB> |
