摘　　要：通过对海底静力触探(CPT)系统的舷外加接杆情况进行力学分析,提出有效的物理方法解决CPT系统水下单元加接杆长度问题。探究了船载布放条件、探杆自身重力和海水流速等对锥杆形态的影响;对锥杆连接体进行了力学分析,以及对配重滑块进行计算;提出了连续接秆、恒力提杆、升沉补偿等关键技术,从而满足海洋工程地质对锥进深度的要求;阐述了加接杆技术在某海上项目的应用情况,验证了此技术的可行性。Through the mechanical analysis of the submarine static cone penetration(CPT)system,an effective physical method was proposed to solve the problem of the length of the extension rod of the underwater unit of the CPT system.The effects of ship-mounted deployment conditions,the gravity of the probe rod and the seawater flow rate on the shape of the cone rod were explored;the mechanical analysis of the cone rod connection body and the calculation of the counterweight slider were carried out;the key technologies such as continuous stalk connection,constant force pole lifting and heave compensation were proposed to meet the requirements of marine engineering geology for taping depth;the application of pole-adding technology in an offshore project was explained and the feasibility of this technology was verified.
