Instrumentation and Monitoring of Tieback Wall on SUM82 at Brecksville
The instrumentation, monitoring, and analysis of a tieback wall located on the western side of the Cuyahoga Valley National Recreation Area (CVNRA) Valley railroad in the vicinity of the State Route 82 bridge over the railroad and the Cuyahoga River, Brecksville, Ohio constitutes the main work of this project. All the elements of the studied tieback wall were provided with instrumentation including strain gages, inclinometers, load cells, and peizometers. The data gathered from all sensors and gages were analyzed, and utilized to validate the developed tieback computer program, and evaluate the present analysis methods. Based on the comparisons of the existing 'Earth Pressure Diagram' analysis methods, it was found that these methods result in considerable discrepancies with measured diagrams. The moments measured along the soldier pile were best fitted when a moment was introduced at the anchor-pile point. A Finite Element Method (FEM) program, PLAXIS, was employed to perform a numerical simulation of the construction of the tieback walls utilizing the inclinometers' readings in the early stage of construction. Then the deduced soil parameters were fixed in the subsequent analysis of various construction stages to accommodate the stress-path dependency of the soil response.
