Buildings Setbacks Research From Surface-Fault-Rupture Statistical Analysis

Abstract:

With the author and others scientific investigation on China Wenchuan Ms8.0 earthquake, China Yushu Ms7.1 earthquake and "China's active fault surveying and earthquake hazard evaluation project" relevant data results and the world requirements about project setback of active faults, etc., this paper concluded that: (1) width of Surface-Fault-Rupture is about 40m by statistics, or from the main surface rupture trace about 20m; (2) width of Surface-Fault-Rupture S and the fault vertical offset V, statistical diagrams and formulas S=8.72+9.01V; (3) Setback of the main surface trace D and buildings from damage index I, statistical diagrams and formulas I=0.7969-0.00231D; (4) based on the first three results and by the actual statistics of accuracy, we get three active fault location accuracy level of the standard i, ii, iii, respectively, the error is ± 5m, ± 25m, ± 60m, also, can give this level of standards of Surface-Fault-Rupture width to the actual engineering applications.
