Soil Nail Walls

Course No. G-12002

Credit: 12 PDH

Course Fee: $299.95 Purchase course

Subject Matter Expert: Vincent D. Reynolds, M.B.A., P.E.

 

Overview

Soil nail walls have been used for over 30 years as an application to improve transportation infrastructure systems. Starting as temporary support for excavation, soil nail walls are now used as a cost-effective alternative to conventional retaining walls. Soil nail walls work by utilizing the tensile strength of steel bars placed into the ground to be supported. The steel bars with the addition of wire mesh, grout, shotcrete, and various drainage applications makes up the soil nail walls.

This course will present to the engineer the design, and construction methods of soil nail walls. Several chapters of the study materials are devoted to failure modes, connections, soil deformation, recommended factors of safety, and construction inspection and monitoring.

This course includes several example problems which will be discussed to aid the student in understanding the design and construction of soil nail walls. Various equations and solutions will be presented in the course materials. The student will learn how to solve for allowable tensile strength, bearing capacity, reinforcement requirements, as well as solve other ancillary equations related to designing soil nail walls.

After reading this 12-hour course, the student will have valuable information that can be used to design cost effective soil nail walls for a variety of transportation projects.

To receive PDH credit, the student will be required to pass a multiple-choice quiz consisting of sixty (60) questions.
