e). Test data showing the rate of pore pressure increase with number of load cycles should be presented. If the behavior of the pore pressure is such that peak to peak axial strains greater than a few percent occur before liquefaction, then the applicant must include the effects of these strains in his assessment of the potential hazards that complete or partial liquefaction could have on the stability and settlement of any Category I structures. Nonseismic liquefaction (such as that induced by erosion, floods, wind loads on structures and wave action) should be analyzed using state-of-the-art soil mechanics principles. Subsection 2.5.4.9. In meeting the requirements of References 3, 6, and 7, the earthquake design basis analysis is acceptable if a brief summary of the derivation of the safe shutdown and operating basis earthquakes (SSE and OBE) is presented and references are included to Subsections 2.5.2.6 and 2.5.2.7. 2.5.4-8 Rev. 2 - July 1981 Subsection 2.5.4.10. In meeting the requirements of References 1, 2, 3, 4, 6, and 7 and the regulatory positions of References 8, 10, and 11, the discussions I of static analyses are acceptable if the stability of all safety-related facilities has been analyzed from a static stability standpoint including bearing capacity, rebound, settlement, and differential settlements under deadloads of fills and plant facilities, and lateral loading conditions. Field and laboratory test procedures and results must be included to document soil and rock properties used in the analyses. The applicant must show that the methods of analysis used are appropriate for the local soil conditions and the function of the facility. Subsection 2.5.4.11. In meeting the requirements of References 1, 2, 3, 4, 6, and 7 and the regulatory positions of Reference 8, the discussion of criteria and design methods is acceptable if the criteria used for the design, the design methods employed, and the factors of safety obtained in the design analyses are
