A i med at the badu ( k343 ) i arge seale i andslide in the nankun railway, geophysical exploration techniques such as seismic reflection of high resolution and geological radar are appi ied to detect the geologic characteristics of the landslide mass including 3d - conformation, perimeter, geometric parameters, si ippage pattern and distribution of displacement field in this dissertation. besides, acoustic method is used for detection of the former anti - slide piles and potency losing causations of the piles are analyzed and the sound geological conditions for upgrade of the piles are ascertained by the above investigations
本文針對南昆鐵路八渡（ k343 ）大型滑坡，運用高解析度反射地震、地質雷達等地球物理探測技術對滑坡體地質進行了詳細的勘測，揭示了八渡滑坡體的空間形態、邊界與幾何參數、滑動方式以及位移場分佈特徵；同時，利用聲波探測對原抗滑樁進行了檢測，分析了失效原因，並查清了擬建抗滑樁地段的地質條件。 -
Synthetic aperture technology origins from radar field firstly. the main reasons for its unsuccessful application in sonar are the low sound speed ( compared with light ), irregular carrier movement and the complexity of underwater acoustic environment
合成孔徑原理最早來源於雷達領域，但它在水聲領域的應用遠不如在雷達領域應用得成功，其原因主要在於水中相對較低的聲傳播速度（相對于光波波速） 、聲吶載體的不規則運動和水聲環境復雜性的影響。
