摘　　要：剖面浮标具有漂流性,难以长期观测固定海域。利用悬索将浮标束缚在固定海域存在的结构体附近,可抑制浮标的漂流性,更好地实现固定海域海洋立体观测,提高对海洋的观测能力。悬索与结构体之间存在两种连接方式——固定连接与滑动连接。以悬链线为基础模型,分析了2种连接方式下悬索的姿态、张力与浮标的观测深度范围,计算了在固定连接条件下对悬索长度、连接位置的要求与滑动连接条件下对结构体倾斜角度的要求。Profile buoys drift freely with the sea current and it's difficult to observe the fixed sea area for a long time.Using the suspension cable to restrain the profile buoy near the structure in the fixed sea area can overcome the drift of the profile buoy,better realize the three-dimensional observation of the ocean in the fixed sea area,and improve the observation ability of the ocean.There are two types of connections between cable and structure–fixed connection and sliding connection.This paper uses the catenary as the basic model to analyze the attitude,tension of the suspension cable and the observation depth range of the profile buoy under the two connection methods.The requirements for the length and connection position of the suspension cable under fixed connection condition and the requirement for the inclination angle of the structure under sliding connection condition are calculated.
