| 1 | Revisiting support optimization at the Driskos tunnel usinga quantitative risk approach显示文摘With the scale and cost of geotechnical engineering projects increasing rapidly over the past few decades,there is a clear need for the careful consideration of calculated risks in design.While risk is typically dealt with subjectively through the use of conservative design parameters,with the advent of reliability-based methods,this no longer needs to be the case.Instead,a quantitative risk approach can be considered that incorporates uncertainty in ground conditions directly into the design process to determine the variable ground response and support loads.This allows for the optimization of support on the basis of both worker safety and economic risk.This paper presents the application of such an approach to review the design of the initial lining system along a section of the Driskos twin tunnels as part of the Egnatia Odos highway in northern Greece.Along this section of tunnel,weak rock masses were encountered as well as high in situ stress conditions,which led to excessive deformations and failure of the as built temporary support.Monitoring data were used to validate the rock mass parameters selected in this area and a risk approach was used to determine,in hindsight,the most appropriate support category with respect to the cost of installation and expected cost of failure.Different construction sequences were also considered in the context of both convenience and risk cost. | J.Connor Langford N.Vlachopoulos M.S.Diederichs | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，2： | 4 |

| 6 | Experimental Evidence for Coverage Preferences in Flood Insurance显示文摘We used a hypothetical choice experiment to estimate the effect of dwelling value and coverage limits on the probability of purchasing flood insurance while holding the probability of flooding and insurance price constant. The results indicate that demand for flood insurance is negatively associated with the amount of insurance coverage. For people assigned higher-valued dwellings, however, the opposite effect is observed. Since more coverage is generally preferred to less, all else being equal, differences in purchase probability dependent on dwelling value indicate an inconsistent approach to home protection. The higher probability of purchasing flood insurance from people in higher-valued dwellings may indicate an investment into the home as a financial asset, a strategy that is not observed to the same extent among people in lower-valued dwellings. This suggests that use of coverage limits may be differentially preferred based on dwelling value, such that low coverage insurance may have lower uptake for those in high-valued dwellings. As Canada evaluates a national flood insurance program, this research suggests that variable coverage maximums could be a way to increase accessibility and uptake of insurance.This research shows an inconsistent demand for flood insurance, dependent on dwelling value and independent of income. | J.Connor Darlington Niko Yiannakoulias | 2022 | International Journal of Disaster Risk Science2022，13，2： | 0 |
