摘要
随着电力能源需求的不断增加,输变电工程建设场地的选址所面临的地质条件越来越复杂,不同于其他工程建设场地,输变电工程建设场地规模不大、工作深度有限,但其一旦受影响,将威胁整个能源供应安全,所以研究一种可靠的、准确的、性价比高的场地稳定性评价方法显得尤为必要。在研究多个建设场地选址的基础上,提出了考虑场地内部抗滑稳定性和场地周边外动力地质作用下的建设场地稳定性评价体系,并在收集已有建设工程场地稳定性评价结果的基础上,将待评价建设场地的稳定性的各评价指标、各影响因素与已有建设场地稳定性评价数据库进行聚类分析,进而对待评价场地进行稳定性评价的一种方法。
With the increasing demand of electric energy,geological conditions of the construction site of power transmission and transformation projects become more and more complex.Different with other construction sites,the sites of transmission and transformation project is not large enough and limited work in the investigation,but the whole energy supply security will be threatened when the site is instability,so it is necessary to study a reliable,accurate and cost-effective project site stability evaluation method.Based on the several project site selections in western Sichuan,the evaluation system of the stability of the construction site under the consideration of the internal stability of the site and the external dynamic geological effect around the site were proposed.On the basis of collecting the evaluation results of the stability of the existing construction site,the evaluation indexes,influencing factors of the stability of the construction site to be evaluated and the stability evaluation database of the existing construction site are analyzed by cluster analysis,and then a method for the stability evaluation of the evaluation site is proposed.
