岩体结构面多源勘测识别方案构建及应用前景探讨

一些重大岩体地下工程设施在其勘察阶段,往往会碰到地形条件比较繁杂的情况,必须对岩体赋存的结构面进行有效勘测识别,否则会致使工程建设与运维过程不确定的风险因素增加。以我国某高放废物地下处置库预选场址为研究载体,在梳理地形条件的前提下,初步构建了结构面多源勘测识别方案,实践证明其能克服多样化地形条件的限制,充分捕获结构面信息。最后探讨了其应用前景,以期为类似工程遇到多样地形时可有效展开地质勘察及识别方案升级提供一些参考。

Seasonal Effect on Atmospheric Refractivity in Diverse Terrains

Air masses in the atmosphere have contrasting temperature, humidity and moisture, which influence radio signals traversing the atmosphere. The influence of the atmosphere on refractivity is strongly determined by its temporal and spatial variability. This paper uses meteorological measurements to investigate the impact of meteorological structures on diverse environments evident in Nigeria. The study hypothesises that refractivity measures could serve as indicators of diurnal radio wave degradation traversing the atmosphere.
