Abstract:
In order to make it clear that the effect of active fault on highway, the activities and the basic characteristics of nine Holocene active fault of the Ningxia region are analyzed, assessment and forecasting index system of active fault on the highway project is determined, and classification standard is established. The indicators are screened and optimized, principal component analysis method is used to determine weight, multi-fuzzy comprehensive evaluation is selected to establishment the evaluation model. Based on ARCGIS9, the spatial database of active fault in Ningxia is built, the current effect of achieve faults on the highway is finished by vector overlap calculating and forecasting assessment of achieve faults of Haiyuan is calculated by raster overlay. The forecasting result is that the area of achieve faults of Haiyuan on the highway with significant influence is 12.34 km2, and 1.0% of the total area of Ningxia; the area with relatively big influence is 271.28 km2, and 21.4% of the total area; the area with middle influence is 400.05 km2, and 31.6% of the total area; the area with little influence is 585.04 km2, and 46.0% of the total area.
