摘    要:2017年受台风影响广东省某堤防部分堤段损毁,总缺口长175 m,灾后相关部门迅速对缺口堤段进行修复。2018年4月,修复堤段出现渗漏,严重威胁堤防安全。物探检测法是堤防渗漏抢险探测的最优手段,但目前物探技术均存在多解性和局限性,为弥补单一探测方法的不足,准确探明堤防渗漏险情,采用高密度电法和探地雷达综合物探技术对险情堤段进行探测,并结合现场检查和设计资料进行综合分析。结果表明:高密度电法和探地雷达综合物探技术能有效探测堤防渗漏险情;推测险情段桩号K0+618和桩号K0+642 m两处存在渗漏通道,堤防浸润界面深约3 m。

关 键 词:综合物探技术  探地雷达  高密度电法  堤防渗漏  抢险探测  险情分析

Abstract:A section of a dike in Guangdong Province were damaged with a total length of 175 m affected by typhoon in 2017, and the damage was quickly repaired after the disaster. In April 2018, the leakage occurred in the repaired dike section, which seriously threatened the dike safety. Geophysical prospecting method is the best technique for emergency detection of embankment seepage; however, it has the problem of nonunique solutions and many limitations. In order to solve the shortcomings of this single detection method so as to accurately detect embankment seepage, the high-density electrical method and ground penetrating radar integrated geophysical prospecting technology were used to detect the dangerous embankment section, and the field inspection and design data were combined for a comprehensive analysis. The results showed that high density resistivity method and ground penetrating radar integrated geophysical prospecting technology can effectively detect the seepage danger of embankment. It is speculated that there are two seepage channels in the dangerous section, located in pile number K0+618m and K0+642m, and the depth of the seepage interface of embankment is about 3 m.
Keywords:comprehensive geophysical prospecting technology   ground penetrating radar   high density resistivity method   river embankment leakage   emergecy detection   dangerous condition analysis
