本文首先定性分析了高密度电法常用装置特性,然后根据软土层厚度探测精度的需要,提出基于钎探或槽探标点校正视深度方法,并基于res2dmod软件正演模拟了温纳α装置、温纳β装置、温纳γ装置、施龙贝格装置的软土层厚度探测地电模型,并说明了施龙贝格装置是最适合实际软土厚度及空间分布探测的装置类型。最后,基于夏蓉高速公路汝城至郴州段第15合同段的K71+520～K71+740m段实测资料,验证了基于钎探或槽探标点视深度校正法和使用施龙贝格装置的优越性。
This paper first qualitatively analyzes the characteristics of high-density electrical method commonly used devices, and then based on the need of soft soil layer thickness detection accuracy, put forward based on solder or groove probe point correction depth of view method, and forward modeling based on res2dmod software Winner α device, WENNER beta device, WENNER γ device and Schnellberg device, and shows that the Schlumberger device is the most suitable device for detecting actual thickness and spatial distribution of soft soil. Finally, based on the measured data of section K71 + 520 ~ K71 + 740m from Rucheng-Chenzhou section of Xia Rong Expressway to section 15 of the Rucheng-Chenzhou section, the superiority of the point-view depth correction method based on soldering or groove probe and the use of the Schlumberger unit is verified Sex.
