摘要

摘要利用斯伦贝谢垂直电测深和二维成像偶极子-偶极子技术,对尼日利亚Akure地区Apatatpiti地区Oloko公路浅层地质物质的类型、性质和基岩结构进行了路面破坏的可能原因评价。二维电阻率结构揭示了薄表土、风化层和风化基底3个岩性层。垂直电测深是在非常低电阻介质的位置进行的,这些介质具有典型的线性特征,例如在二维电阻率结构的某些距离上的裂缝/断层。地电剖面确定了表层土、粘土/砂质粘土、破碎基底、风化/新鲜基底4个地质层。地电剖面和二维电阻率结构显示,构成路基的上部0-6m具有低电阻率(36 Ωm ~ 108 Ωm),特征为粘土材料,暗示存在可能影响道路稳定性的薄弱带。靠近公路的4口井距地下水位较浅,深度在3.7 ~ 4.29 m之间。因此,路面破坏的可能原因是较厚的低阻层、近地表线状特征疑似裂缝/断层、地下水位较浅。

Subsurface Investigation for Road Construction Using Electrical Resistivity Method along Oloko road, Apatapiti, Akure, Ondo State, Nigeria
Abstract Evaluation of the shallow geologic materials in terms of types, nature, and bedrock structure as possible causes of pavement failure was carried out along Oloko road Apatatpiti, Akure, Nigeria, using Schlumberger vertical electrical sounding and 2-D imaging dipole-dipole techniques. Three lithological layers, namely thin top soil, weathered layer and weathered basement, were revealed by the 2-D resistivity structure. Vertical electrical soundings were made at locations with a very low resistive medium typical of linear features such as fractures/faults at some distances on the 2-D resistivity structure. Four geologic layers, namely the top soil, clay/sandy clay, fractured basement, weathered/fresh basement, were identified by the geoelectric section. The geoelectric section and the 2-D resistivity structure revealed that the upper 0-6m, which constitutes the subgrade, has a low resistivity (36 Ωm to 108 Ωm) characterised to be clayey materials and suggestive of weak zones that might impair the stability of the road. A relatively shallow depth, ranging from 3.7 m to 4.29 m, was the depth to the water table of the four wells close to the road. Therefore, the possible causes of pavement failure are the thick and low resistive layer, the near-surface linear features suspected to be fractures/faults, and the water table’s shallow depth.
