Engineering Geological Investigation

Compared with conventional airborne remote sensing application to engineering geological investigation, High precision Unmanned Aerial Vehicle Remote Sensing (UAV-RS) technology can improve work condition with advantages of high flexibility, low cost, high efficiency and up-to-date situation acquisition. Especially, it has very important engineering significance for quick and urgent geological disaster reconnaissance along transportation lines. In the paper, some aspects of application to transportation-line (pipeline, highway and railway) engineering geological investigation were discussed. The concerned key points, including components of UAV-RS system, data processing workflow and image interpretation were analyzed. As a case study, a UAV-RS application project for transportation-line geological disaster investigation was given. The utilization of this new remote sensing technology successfully collected and discovered potential geological disasters and provided scientific data for timely decision-making.

The Stability

A large-scale accumulation body, lying in left bank of a hydropower station dam, its stability is directly related to dam construction and operation. By means of engineering geological investigation on geological characteristics and geneses of accumulation body, the result shows the accumulation body is generally stable. Then, safety factor of accumulation body under different working conditions are calculated separately according to the method of EMU, The result shows that side slope is wholly stable and it can meet the stability requirements while the stability of section Ⅲ needs more studies. 3D model is built and applying FLAC program on stability of accumulation body under diverse conditions, it also shows that the whole stability of accumulation body is in a comparatively good condition. However, the possibility of partial slide still exists, and for this reason corresponding protections and reinforcements are proposed at last.
