Project Description

The Southeast Stoney Trail Bridge structure in Calgary, AB is a 70-degree skewed, 48-metre long, single-span highway overpass that was constructed in 2012.  Rehabilitation works on the bearings and finger joints were performed in 2020; subsequently, additional movements were noted at both abutments.

The project, carried out by AllNorth as the structural engineer, involved reviewing the bridge conditions and providing additional rehabilitation recommendations.

Our Role

RAM’s Geotechnical Engineering group was retained for, and provided, the following services:

• reviewed available information, including design drawings and reports for the abutment/MSE wall design;
• using the available information, prepared computer models of the MSE wall and pile-supported abutment using geotechnical analytical software;
• provided design input to AllNorth for the preparation of a structural analysis model, including soil springs (e.g. p-y curves) of the MSE wall reinforcement developed from the geotechnical models, lateral earth pressure from soil on the abutment, wing walls, and piles and anticipated deflection of the MSE walls.
