渭南市位于华北地台鄂尔多斯地块南缘渭河断陷盆地中西部，固市凹陷西南缘，地貌单元主要为渭河漫滩和Ⅰ、II、Ⅲ级阶地。通过钻孔勘探、剪切波速测试、地基土的物理力学性质及地脉动测试，结合场地地下水等资料，将小区划场地划分为四个Ⅰ级工程地质亚区和九个II级工程地质段，从而为地震小区划场地设计地震动参数和评价场地地震地质灾害提供基础资料。

Weinan city is in located in the midwest of Weihe rift basin, southe west margin of Gushi depression, southern margin of the Ordos block in the north china platform.The main geomorphologic units is the floodplain, the first terraces, the secondary terraces and the third terraces of Weihe river. By using the drilling exploration, the shear wave velocity tests, the character of physical mechanics of foundation soil, the ground-micro-tremor-signals tests and the groundwater, we divided the micro-zoning site into four engineering geological area of level Ⅰ and nine engineering geological section of level II, Which provides the basis material for the design ground motion parameter and seismic geological hazard evaluation in site.
