关中盆地主要活动断裂分级及工程建设适宜性评价
|
摘要
为关中城市群的规划建设中的活动断裂场地提供工程评价标准。依据关中盆地活动断裂的分类和分级为基准,对关中盆地活动断裂场地的工程建设适宜性评价采用定性分析和定量计算结合的综合评价方法。将活动断裂的场地稳定性分为不稳定、稳定性差、基本稳定和稳定4级;关中盆地活动断裂场地的工程建设适宜性亦定性为4级,依次是不适宜、适宜性差、较适宜和适宜;定量确定不同类型和级别活动断裂的安全避让距离,从而确立了与关中盆地26条活动断裂的工程建设适宜性评价标准。
Provide engineering evaluation standards for active fracture sites in the planning and construction of Guanzhong urban agglomerations. Based on the classification and grading of active faults in the Guanzhong Basin, a comprehensive evaluation method combining qualitative analysis and quantitative calculation is adopted for the evaluation of the suitability of the construction of the active fault site in the Guanzhong Basin. The site stability of active fracture is divided into unstable, poor stability, basic stability and stable four levels. The suitability of the construction of the active fault site in the Guanzhong Basin is also classified as four grades, which in turn is unsuitable, poorly suitable, a little suitable and suitable. Quantitatively determine the safe avoidance distance of different types and levels of active faults, thus establishing the evaluation criteria for engineering construction suitability of 26 active faults in Guanzhong Basin.
