Chapter 14 of the WisDOT Bridge design Manual and Section 11 of the AASHTO Specifications. There are two aspects to the design of retaining walls. The first is the internal stability of the wall. Here the various components of the wall must be designed so that the wall will maintain its shape and integrity for its design life. The second aspect is the external stability of the wall. Here the soil and surcharge pressures acting on the wall must be analyzed to determine if the& ...

Understanding the properties and characteristics of soils is key to building better walls. Different soil types will dictate the amount of time needed for compaction, the amount of reinforcement required, and potentially the cost of the retaining wall. Check the on-site soils carefully before beginning, and get a written identification of the soil type. A soils report from a local engineer will be required before a design and/or permit is issued for most retaining walls above 4 ft. (1.2 m). See the& ...

This report presents the results of the geotechnical investigation Southern California Soil and. Testing, Inc. (SCS&T) performed for the subject project at the Rosemary's Mountain Quarry. We understand the project consists of the expansion of the existing quarry to the north, the design and construction of mechanically stabilized earthen (MSE) retaining walls during mining phase 2, and the creation of a relatively large mining waste dump behind the planned cut slope during.
