• A PRACTICAL GEOTECHNICAL RELIABILITY BASED DESIGN EMPLOYING RESPONSE SURFACE -SESIMIC DESIGN OF IRRIGATION CHANNEL ON LIQUEFIABLE GROUND-

抄録

 The paper proposes a simple and yet practical reliability based design (RBD) scheme which takes into account the characteristics of geotechnical design. The proposed scheme evaluates the reliability by basically separating the geotechnical analysis and the uncertainty analysis, and reuniting them by the response surface (RS) and Monte Carlo simulation (MCS). As a result, RBD can be easily done making the best use of geotechnical analysis tool newly developed. The philosophy and procedures of the scheme are presented through a real and complex geotechnical structure design, i.e. seismic design of 12 km long irrigation channel against liquefaction. Through this design example, merits of the geotechnical RBD are shown, such as amount and quality of investigation data on the reliability evaluation, major sources of uncertainties in RBD, and suggestions for priority of countermeasure locations and additional investigations.
