Tieback walls are used to stabilize railroad embankments. Frequently, they can be built without interrupting traffic or relocating the tracks. The walls eliminate the temporary excavation support that may be required to construct other methods of stabilization. They may be built close to tracks or structures because they limit long-term soil movements. Tieback walls can stabilize embankments with deep failure surface. The design of a tieback wall for a railroad embankment is performed in a manner similar to that of other tieback walls. A geotechnical investigation should provide the design properties including location of the failure surface, unit weights of material, internal strength properties of material, strength properties along the failure surface, soil or rock classification, and groundwater information. In addition, tests must be made to determine the levels of corrosion protection that will be adequate to ensure that the tieback and the wall components will not corrode. A railroad embankment in the Blue Ridge Mountains was stabilized with a tieback, driven H-pile wall 40 ft high. Track traffic was not interrupted and future maintenance was reduced. Monitoring of the wall has indicated that it is performing as expected.
