一、前言海上的高大建筑设计,不仅要考虑到十米高处的平均风速,还必须较精确地了解风速随高度的分布。一般来说,从海面到50米左右这一高度,称为近海面层。由于人们的海上生产活动多发生在这一层中,对这一层的研究也就更加深入、细致。理论和实践都已证实,这一层中风速随高度的变化在中性大气层结下,呈对数分布;在层结大气中,需对对数廓线加以稳定度修正。风速垂直分布是十米高处平均风速,大气稳定度和下垫面粗糙度的函数。在海
I. Introduction The tall building design at sea must not only take into account the average wind speed at the height of 10 meters, but also must know the distribution of the wind speed with height more accurately. In general, from the sea to the height of about 50 meters, known as the surface layer. As people in the marine production activities occur in this layer, the study of this layer will be more in-depth and meticulous. Both theory and practice have confirmed that the wind speed in this layer varies logarithmically with the change of altitude under the neutral atmosphere. In the stratified atmosphere, the stability of the logarithmic profile needs to be corrected. The vertical distribution of wind speed is a function of mean wind speed, atmospheric stability and underlying surface roughness at a height of ten meters. In the sea
