主要研究內容包括：一、總結分析了當前水下導航的常用方法和不足之處，指出基於航位推算的導航方法，存在著最大的問題就是導航誤差的積累問題，如果沒有修正系統，這種方法很難滿足使用要求；其次指出基於聲學的導航方法，造價昂貴，導航范圍有限，難以滿足自主水下航行器大范圍導航的需求；二、總結了當前水下地形輔助導航的主要技術路線，一是基於地形高程的匹配方法，這是當前研究的重點；二是基於地形圖像的匹配方法，由於缺乏良好的圖像傳感器，和可用的海底圖像地圖，目前這種方法還有待研究發展；三、將兩種地形高程匹配的常用方法應用到自主水下航行器上：以相關演算法為前提的地形輪廓匹配（ tercom ）方法和以卡爾曼濾波為基礎的桑迪亞慣性地形輔助導航（ sitan ）方法，前者演算法簡單可靠，但是導航精度不高，後者雖然精度比較高，但存在著演算法較為復雜、有可能發散和出現奇異值等問題。( 6 ) conclusion was obtained by the analyzing the mechanics environment and the stability of the lanslide on the right bank after the dam built : the value of the rock mass stress increased and the tensile stress region obviously reduced, the direction of the principal stress was unchangeable the dam and the landslide were stable under the dangerous condition ( the reservoir and at the same time the earthquake was viii ), but when the water lever suddenly fell and did not think of other force, safe factor evidently reduced, the dam and the landslide will be destroyed under the most dangerous condition ( the water lever suddenly fell and at the same time the earthquake was vi ) ; the stability of the landslide will be destroyed by the horizontal thrust under the most dangerous condition or ; the physical and mechanical parameter will be reduced due to long period filter, the landslide will be destroyed too
（ 6 ）建壩工程荷載條件下河谷巖體力學環境分析及右岸古滑坡體的穩定問題分析得出：建壩后河谷的巖體應力量值明顯增高，同時左岸的張應力區的范圍及量值明顯減小，主應力的方向依然與模型的底邊界垂直；大壩建成后逐漸蓄水階段以及同時考慮本區最強地震力的作用等各種不同的工況條件時，滑坡體及壩體總體上仍處于穩定狀態；水位驟降時，在未考慮其他外力作用的情況時，滑體的安全系數將顯著降低。若考慮水位驟降及本區最大地震力的共同作用，壩體將在滑坡體下滑推力的作用下產生破壞；建壩后水平推力對右岸古滑坡體穩定性的影響分析可以看出，在最危險的工況條件下，壩體及滑坡體也將處于臨界狀態；在長期滲透變形的作用下，由於滑帶的物理力學參數的降低而有可能導致壩體失穩破壞。Real time seafloor tracking technique is the critical technique to ensure smooth seafloor surveying with full coverage and high efficiency. after detailed investigation on stochastic features of seabed reverberation produced by mbss systems, the author presented an algorithm and a set of relevant key coefficients for real time seafloor tracking, taking into account of characteristics of signal processing and timing sequence of the real system and introducing theorems of terrain surveying. as an achievement, a mathematical model was established based on the technique of centered filtering
