Assessment of the Design Displacement Values at Seismic Fault Crossings and of Their Excess Probability

Journal of Mountain Science 2011年第2期8卷 228-233页

Line structures such as pipelines that cross active faults should be designed to retain leak-tightness if the design displacement (Ddesign) occurs. Principal approaches to the Ddesign and rupture kinematics assessment are described. They are based on relationships between earthquake magnitude, rupture length and displacement, and on the detailed field data on a specific fault that crosses the pipeline route. Since the future offset at the crossing may exceed the design value, the probability of a displacement occurrence where the safety of the structure can not be ensured should be estimated. Assessment method on such event probability is described and exemplified through active fault studies carried out at several pipeline projects in Russia.

The work is devoted to a problem of seismic activity of northern part of Sakhalin *** active faults were trenched and studied in *** expressiveness in a relief and character of displacement of strata is *** provide cogent evidences that young tectonic faults on Schmidt peninsula were formed as a result of sharp periodic motions with amplitudes up to several meters and are connected with strong *** urgency of work is that there are works on search of hydrocarbons
