高分辨率浅层人工地震勘探探测隐伏断裂实例

Case of High-resolution Shallow Artificial Seismic Exploration Used for Buried Fault

摘要:

利用高分辨率浅层地震勘探反射波法探测了福建某火电厂场址内的隐伏断裂。结果表明断裂显示清楚,为一走向NE40~55°,上断点埋深为11 m和31 m,断距2~4 m的正断层,为工程避让提供较可靠的依据。

Abstract:

Using the high-resolution shallow seismic reflection, a buried fault in the site of thermal power plant in Fujian province is explored. The result reveal that the fault exists clearly with strike of N40-50°E. It is a normal fault with about 2-4 m throw, and its two breakpoints are buried in 11 m and 31 m depth. The shallow seismic exploration and geological interpretation offer dependable basis for engineering avoidance
