The results show that, with the increase of the structure stiffness, the vertical displacement decreases. Owing to the small depth of a box-typed VLFS, compared with the expense caused by increasing structure stiffness, the decrease of vertical displacement is not valuable. It can be deduced that the flexibility of VLFS is caused by its principal dimensions . The increase of transverse section modulus does little good to the whole stiffness.

研究发现，随着浮体结构刚度的增加，结构的垂向位移值随之减小，但由于箱式超大型浮体结构的型深较小，与结构刚度增加所付出的代价相比，结构垂向位移减小的效果不明显，由此可知，超大型浮体结构的总体柔性是由于其巨大的主尺度造成的，横剖面剖面模数的增加对结构整体刚度的改善作用不明显。
