Reinforced retaining structures consist of many advantages in comparison with rigid retaining structures. Generally, the use of reinforced retaining structures can tremendously reduce the construction cost and shorten the construction period. Since reinforced retaining structures are flexible type structures, which can sustain large amount deformation without damaging their stability. However, improper design will cause fatal failure of retaining structures.
The objective of this thesis study consists of investigating the construction practice and cost analysis of reinforced retaining structures. In addition, the construction and materials specifications associated with the reinforced retaining structures are also investigated in the study.
There are several types wall facings are commonly used for reinforced retaining walls, which include cast-in-place concrete facing, wrap-around, modular block, precast panel, timber column facing, and others. The construction details and procedures, and monitoring program for these types wall facings are discussed. The construction cost for various types wall systems is investigated. The analyzed items include labors, materials, equipments, maintenance, and management.
The construction cost for conventional wall systems and reinforced retaining walls is also investigated. Case study locations include local area, America and Mainland China. The on-site inspection and material specifications for geosynthetic reinforced retaining wall systems are discussed. Five design specifications, such as BS8006 and BE 3/78 of United Kingdom, French NF P 94-220, Germany DIBT, and American Federal Highway Administration (FHWA), are compared in the study
It is expected that the results of the study would provide a useful reference for engineers to improve the design and construction of reinforced retaining wall systems.
