摘要
针对某港口堆场竣工即发生滑坡的工程案例,运用快速无损的探地雷达设备,对滑动区范围和滑动深度进行探测。探讨滑坡区内外土层的探地雷达探测机理,分析推断滑坡区域和滑坡深度。探地雷达探测推断的该工程滑坡范围、滑动面深度与现场静力触探试验结果和圆弧滑动稳定计算得到的滑动面基本吻合。应用探测结果设计的加固工程运行正常,说明了探地雷达方法探测滑动范围的有效性,可为滑坡治理设计提供科学依据。
Ground Penetrating Radar is used to detect the district and depth of landslide of a new port. It is discussed the detecting mechanism of GPR for the soils inside and outside the landslide district. The landslide district and depth are analyzed and given. The detecting sliding depths are consistant with the re- sults of field cone penetration test and the sliding surface is the same as the results of stability calculation by circular silp method. The yard can be safely loaded to design height after treatment on basis of the re- sults of GPR These indicate that the GPR is an effective tool for detection of the sliding district.
