摘要
针对输变电工程建设场地的区域构造稳定性评价问题,从地质结构、断裂活动、地应力特征及地震条件方面确立14个影响因子,构建区域构造稳定性评价指标体系。以专家打分法确定因子权重,对定性指标进行量化取值,经过对指标评价量值的规一化处理而确定指标评价的基本值。收集已有场地区域构造稳定性评价数据,通过聚类分析,最终确定待评价场地区域构造的稳定性状态。按此方法,评价甘谷地输变电工程建设场地的区域构造稳定性,获得的评价结论为"较稳定",与场地实际运营情况基本一致。
In order to evaluate regional structural stability of power transmission and substation construction sites,the evaluation index system for regional structural stability is established based on the determined 14 influencing factors such as geological structure,fracture activity,geo-stress characteristics and seismic conditions.Factor weight is determined by Expert Scoring Method,and the qualitative indicators are quantitatively valued;the basic value of index evaluation is determined by normalizing the value of index evaluation.Assessment data of regional tectonic stability in existing field areas are collected and final determination of the stability state of regional structure in the field is evaluated by cluster analysis.In this paper,the regional tectonic stability evaluation of power transmission and transformation project site,Gangu site is taken as an example.The evaluation conclusion is"relatively stable",which is consistent with the actual site operation.
