摘要:

在城市道路塌陷隐患探测中,相邻车道地下介质差异性较小,其探地雷达剖面之间具有较高的一致性和关联性,为了提高探地雷达资料解释的准确性和速度,综合对比分析相邻车道探地雷达剖面之间的相关性,提出了探地雷达多剖面联合解释方法,首先同时对多个相邻车道探地雷达剖面中的塌陷隐患病害同步进行分类和分级判释,然后将每个病害异常输出为单体病害文件至单体病害文件库,并基于人机交互方式对单向或双向多车道探地雷达剖面中的任意病害类型或病害等级进行综合统计、自动排序,可用于生成严重病害的现场加密复测验证单和最终的检测报告.结果表明:探地雷达多剖面联合解释方法能够同时对多个相邻车道探地雷达剖面同步进行对比分析、相互验证,能有效克服单剖面信息量不足的局限性,不仅可以快速辨别和剔除外界干扰形成的虚假异常,减少多解性,而且可以估算地下病害异常的面积范围和空间展布,有效提高解释的自动化、准确性和可信度,明显加快解释速度.

Abstract:

In the detection of urban road hidden diseases, the underground media of adjacent road lanes are less different, and it’s high consistency and correlation between the profiles of Ground Penetrating Radar (GPR). In order to improve the accuracy and speed of GPR data interpretation and compare and analyze the correlation between GPR profiles of adjacent lanes comprehensively we propose a method that named multi-profile integrated interpretation method. Firstly, it’s carried out simultaneously that classifying and ranking the hidden dangers in multiple adjacent lanes GPR profiles. Secondly, each disease abnormality is output as a single disease file to the disease-file-library, and any disease with different type or level in the one-way or two-way multilane GPR profile is automatically sorted based on the human-computer interaction mode of the GPR multi-profile interpretation system, and it generates on-site retest verification tables and test reports of serious diseases. The results show that GPR multi-profile interpretation method can not only compare and analyze multi-profile comprehensively at the same time and overcome the limitation effectively of single profile with little information, but also eliminate false-anomalies formed by surrounding interference and reduce the probability of multi-solution. We can estimate the area and spatial distribution of subsurface disease anomalies quickly by the method and improve the degree of automation effectively, accuracy, credibility of interpretation, and shorten the time of interpretation obviously.
