摘要
本文的研究结果是建立了一种采用电阻率法-双偶极子法和电磁法-甚低频法对道路破坏进行地球物理处理的统一方法。这项工作沿着翁多州的Oke-Agbe公路进行。计算机对研究区域的数据进行了迭代，将研究路段划分为高风化区和非风化区，电阻率值在37 - 595 Ωm之间。本研究中确定的道路破坏形式是由于与粘土、相当厚、岩土薄弱和低电阻率近地表水平相关的不同沉降引起的沉降。研究结果清楚地表明，该研究在公路可行性研究和道路评价中具有重要意义。JONAMP Vol. 11 2007: pp. 411-414
Geophysical investigation of Oke-Agbe-Oyin Road failure using VLF and double dipole
The result of this paper is to establish a consistent approach to geophysical handling of road failure using electrical Resistivity method-Double Dipole and Electromagnetic method- VLF (Very Low Frequency). The work was done along Oke-Agbe Road in Ondo State. Computer iterated data from the study area enabled the delineation of the investigated portion of the road into highly weathered and non weathered zones with Resistivity values ranging from 37 – 595 Ωm. The form of road failure identified in this study is due to subsidence arising from differential settlements associated with clayey, fairly thick, geotechnical weak and low resistivity near surface horizon. The results obtained clearly demonstrates the relevance this kind of study in highway feasibility studies and roadway evaluation. JONAMP Vol. 11 2007: pp. 411-414
