摘要
随着我国经济的快速发展,环境形势日益严峻,清洁能源迎来前所未有的发展机遇,国家电力需求愈加迫切。近年来在各类发电和输电设施快速建设的同时,对勘察深度也提出了更高的要求。在凉山地区,岩溶强烈发育,溶洞分布广泛,且形状不同大小各异,构造非常复杂。本文以凉山地区某特高压输电线路中典型工程实例,阐述了探地雷达在岩溶发育地区输电塔基勘察中的应用,通过探地雷达精细勘察与钻探相结合进行塔基选址,为最大程度优化基础设计方案、节省建设成本提供可靠依据。
With the rapid development of China's economy,environmental protection situation is increasingly severe,Clean energy ushered in unprecedented opportunities for development,and the national electricity demand is more urgent.In recent years,with the rapid construction of various types of electric power facilities,the requirement of survey depth is higher.In Liangshan area,karst is intensely developed.Karst caves are widely distributed,with different shapes and sizes,and their structures are very complicated.In this paper,we describe a typical engineering example of UHV transmission lines in Liangshan area,and elaborate the application of GPR in the karst area of transmit electricity tower foundation.Combining the methods of GPR and drilling exploration for tower location,which can provide a reliable basis for optimizing the basic design scheme and saving the construction cost.
