高层建筑石灰岩基底的雷达探测研究

Application of Ground Penetrating Radar for Limestone Foundation of High Building

基岩在地下空间的起伏分布是石灰岩地区高层建筑基础设计施工前必须准确了解的关键信息,以马来西亚吉隆坡某拟建高层建筑为例,利用探地雷达对石灰岩基底进行探测试验,并进行数据处理及雷达图像解释分析,雷达探测剖面的解释结果与验证钻孔所揭示的数据基本一致;结果表明,在石灰岩地区,利用该方法可有效地获取石灰岩基底的起伏分布,为基础设计和施工提供依据。

It is necessary to acquire topography of the limestone before high building foundation design in limestone areas. The ground penetrating radar method was introduced to detect the limestone interface for some high buildings in Kuala Lumpur. Some process and analysis on obtained ground penetrating radar image were carried out, and the interpretation resuit was verified by testing borehole data. Testing results show that the ground penetrating radar is a good way to detect limestone topography, and it is a great help for the foundation design and construction.
