“…The model gives improved predictions of anchor capacity for both frictional and cohesivefrictional soil cases based on the mean and the COV of resistance bias values, where bias is the ratio of measured to predicted anchor loads. Finally, the bias statistics computed in this paper can be used as a starting point to calibrate the limit state function for the ultimate capacity of MAW plate anchors in reliability-based designs as shown by Bathurst et al (2011b …”

“…Ideally, a model that gives predicted and measured values that are close to or slightly above the one-to-one correspondence line is desirable. This is particularly true if the long-term objective is to carry out load and resistance factor calibrations for the ultimate anchor capacity limit state (Allen et al, 2005;Bathurst et al, 2008Bathurst et al, , 2011aBathurst et al, , 2011b). …”

“…An additional beneˆt of this approach is that the same bias value statistics can be used as a starting point for carrying out reliability-based calibrations of limit state equations in limit states design practice (Allen et al, 2005;Bathurst et al, 2008Bathurst et al, , 2011a. In fact, the incentive toˆnd a more accurate anchor plate capacity model was prompted by the need for better bias statistics in a complimentary rigorous reliability-based calibration study for the ultimate limit states design of the anchors used in MAW structures (Bathurst et al, 2011b).…”

“…In this section, an example to select the best from a non-reinforced embankment, an RC-retaining wall, and a reinforced wall will be shown. On the basis of the current design, the primary condition is assumed and the lifecycle cost is estimated under Bathurst et al (2011) the analysis condition shown in Table 12.3. Figure 12.19 shows the analysis result; it shows the relation between the estimated lifecycle cost and the structure height.…”

As a country affected by frequent earthquakes, Japan has accumulated experience on using reinforced soil wall technology as a seismic countermeasure. This paper briefly reviews the recent development of this technology in Japan. Approximately 1,600 case histories on the seismic performance of such walls during the 2011 Great East Japan Earthquake were collected and analyzed. Statistical data on the seismic damage revealed that all types of reinforced soil walls performed well during the 2011 earthquake. The case study where the damage was closely investigated was also particularly focused upon and discussed.In current infrastructure projects, the most economical solution with the required performance is selected from several candidate solutions. In general, the term "most economical" implies that the initial cost is the lowest for that particular solution. Risk-induced seismic events are not usually considered in many projects. In this paper, a new design concept that considers the lifecycle cost including the geo-risk for a reinforced soil wall is proposed. A user-friendly cost estimation tool and a reliability analysis method along with its validation are also introduced. As a practical application of the geo-risk-based design, the selection of the best solution from the candidate solutions and the determination of the optimum reinforcing condition are discussed.
