摘要
本文比较了冰力现场量测的直接法和间接法,针对间接量测法,提出了用于多自由度体系的、由结构加速度响应及应变响应反求冰力的反序计算法,并分别编制了两套计算机程序,一套是利用加速度响应反求冰力的;另一套是利用应变响应反求冰力的。同时,还利用渤海辽东湾JZ20-2导管架平台1:50的模型实验,证明了本文提出的用结构的加速度响应和应变响应反求冰力的计算原理和程序的正确性。
la the paper, the reverse method of ice force estimation is developed and the comparison of reverse method with direct method of ice force field measurement is made.With the reverse method, the ice forces can be calculated from the acceleration or strain responses of a multi-degrees of freedom structure acted by ice. Two sets of calculation programmes are composed. In order to verify the method as well as the computer programmes, the model tests are carried out using the 1:50 scale model of a jacket platform JZ20-2 in the Liaodong Bay. The results of the tests show that the reverse method and the programmes are correct and practical.
