沈阳—抚顺地区位于国家地震强烈区划图中的七度地区范围内,为该区的城市规划和场地选择,必须很好地解决地震工程地质问题。本文包括三个组成部分:1.地震背景及危险区予测,2.强震效应的场地工程地质分析,3.该地区主要地震工程地质问题及其评价。文章表明,该区存在三个5—6级地震危险地区。通过场地地震工程地质条件的研究,应用地面运动反应分析理论和方法,确定了该区地面运动基本参数和场地动力特性的分布规律。最后,对场地条件及地震工程地质问题做出了评价。在此基础上,对沈阳—抚顺两城市未来可能发生的地震灾害影响做出了予测。
Shenyang - Fushun region is located within the scope of the seven-degree region in the strong regional zoning map of the country. For the urban planning and site selection of the region, the seismic engineering geological problems must be well solved. This paper consists of three components: 1. Earthquake background and danger zone to be measured, 2. Strong earthquake effect site engineering geological analysis, 3. Major earthquake engineering geological problems in the area and their evaluation. The article shows that there are three dangerous areas of magnitude 5-6 in this area. Through the study of geological conditions of site seismic engineering, the ground motion analysis theory and method are applied to determine the distribution of the basic parameters of ground motion and the dynamic characteristics of the site. Finally, the site conditions and seismic engineering geological problems have been evaluated. On this basis, the possible impact of the earthquake disaster on the Shenyang-Fushun City was predicted.
