摘要
修建公路时,有必要了解勘查路段近地表层断层、裂隙的赋存状态,为下一步公路施工设计提供地球物理依据。否则在施工中因地表层断层、裂隙等原因引发地面塌陷等地质灾害,轻则影响施工进度,给施工方造成经济损失,重则危及人员的生命安全。通过实例介绍高密度电法勘探在公路路基断层、裂隙勘探中的有效应用。
When building a highway, it is necessary to understand the occurrence of faults and fissures in the near surface layer, which provides the basis for the next step of the highway construction design. Otherwise, in the construction of surface layer due to faults, cracks and other causes of ground subsidence and other geological disasters, the impact of light on the construction schedule, to the construction side caused economic losses, serious damage to the life and safety of personnel. The article introduces the application of high density electrical prospecting in the highway subgrade fault and fracture exploration.
