摘要
针对道路病害体探测干扰因素多、施工环境复杂等特点、以Greater Bay Area澳门特别行政区道路探测为例,探讨三维探地雷达和地震映像对道路病害体的探测效果。在数据采集过程中,采用分时采集、现场地标打点等措施克服车辆干扰及测量信号不稳等问题;在资料处理过程中采取多种去噪技术联合去噪,重点采用了常规滤波、一维滤波、二维(F-K域)滤波、多道中值滤波等去噪方法,最大程度提高信噪比。经过综合解释,探测到空洞、疏松体、富水体不同类型病害体6处,通过钻探验证,探测成果准确可靠。实践证明,三维探地雷达技术和地震映像技术在澳门特别行政区道路探测中的综合应用,为类似于交通繁忙、干扰种类复杂等条件下道路病害体探测提供了范例。
Considering the detection of road hazards has characteristics of multiple interference factors and operation environment complex etc,taking the Macao SAR in the Greater Bay Area road detection as an example has discussed 3D ground penetrating radar and seismic reflex road hazards detection effects.During the data acquisition process,time-shared acquisition,site landmark plotting etc measures have been used to overcome vehicles disturbance and measuring signal unstable issues.During the data processing,multiple techniques joint denoising,emphasis has put on routine filtering,1D filtering,2D(F-K domain)filtering and multi-channel median filtering etc denoising methods,extremely promoted S/N ratio.After comprehensive interpretation has detected cavity,loose mass and water-rich mass etc 6 different hazardous masses;through drilling verification,the results are accurate and reliable.Practices have testified that the integrated 3D ground penetrating radar and seismic reflex technologies used in the Macao SAR provided example for similar road hazards detection in traffic very busy,interference complex areas.
