小尺度水域精细化探测技术在黄河天桥水电站除险加固工程中的应用
|
摘要
该文介绍了小尺度水域精细化探测技术的基本构成、探测原理、探测水下地形、基岩的技术要点、探测装备、探测程序和数据处理方法,尝试了探测成果直接应用于工程设计的新途径。通过天桥水电站除险加固工程护坦及其延长部位探测的成功案例,说明采用这一新技术开展水下勘探的可行性,分析总结了在实际探测工作中的适用条件、应注意的问题以及经验和认识。
It introduces the basic structure and detecting principle of fine detecting technique on small size water area.It also introduces the key points and program of the technique,the detecting equipments and data distinguishing & processing when detecting underwater topographic and bed rock,and the detecting results are attempt to apply directly in project design.With the successful example of risk elimination and strengthening projects aprons and the prolonged parts detection in Yellow River Tianqiao hydropower station,it shows the feasibility of detecting underwater topographic and bed rock with the new technique;finally the applicable conditions the problems that should be taken attention,experience and knowledge are analyzed and summarized during the practical detection work.
