摘　　要：基于压力和密度的近似计算被广泛应用在海洋工程施工中,是一种利用测量海水压力值计算深度的简便方法.本文回顾了几种基于压力和密度的不同近似计算方法,并将它们与流体静力学方程的解算数值进行了比较.结果表明,在计算绝对深度时,应使用基于密度和压力的静水力学计算方法或完整的联合国教科文组织(UNESCO)发布的压力到深度公式,两者可提供相似的结果.The approximation calculation based on pressure and density is widely used in marine engineering construction,and it is a convenient method to calculate the depth by measuring the pressure value of seawater.This paper reviews several different approximation calculation methods based on pressure and density,and compares them with the solution values of hydrostatic equations.The results show that the hydrostatic calculation method based on density and pressure or the full pressure to depth formula published by the United Nations Educational Scientific and Cultural Organization(UNESCO)should be used for calculating absolute depth,both of them can provide similar results.
