ASSESSMENT OF RELIABILITY AND INHERENT RISK LEVELS OF GEOGRID REINFORCED SOIL STRUCTURES (2011)
Geogrid reinforced soil structures are planned and constructed in increasing amounts due to their various benefits. Little amounts of failures or deformations beyond serviceability limit state are reported. Multiple factors can influence the behavior of reinforced walls and elements that cause risk and reduce reliability have to be assessed. All aspects contributing to reinforced walls as roles and responsibilities, site investigation, applicability of the structure, design methods, materials as well as construction are evaluated and their reliability and risk levels regarding structural behavior investigated. Identification of roles and responsibilities will be assessed as part of the risk assessment under the light of outsourcing and subcontracting. Apart from these influences the construction process will be looked at and conclusions drawn.
