海床土体剪切波速(
V
s
)是确定海床场地设计地震动参数及土‑海洋工程结构体系动力分析所必须的一个基本的土动力参数。结合某伶仃洋跨海通道海床钻孔实测
V
s
剖面,基于目前现有的研究成果,分别采用线性模型、二次多项式模型、幂函数模型和对数函数模型对比分析了陆域土
V
s
与深度
H
的经验关系式对该海域土
V

的适用性,得出结论如下:
V

‑
H
关系的二次多项式模型适用于该海域砂类土(粗砂、细砂、粉砂)
V

的预测,
V

均随
H
的增大而增大;现存的陆域土

关系不适用于该海域黏性土(粉质黏土夹砂、粉质黏土)
V
s
的预测。引入土的密度
ρ
作为另一变量,建立了基于双变量
H
和
ρ
的海域黏性土
V
s
的预测模型。此外,该海域淤泥和淤泥质土由于埋深较浅、土质柔软,其
V

与

无明显的相关性。该成果可为伶仃洋海域工程建设中海床土体

的确定提供科学的预测依据。
The shear wave velocity
V
s
plays a critical role as a fundamental indicator of soil dynamic properties, especially in the context of s. This information is essential for establishing design ground motion parameters for seabed sites. In this study, combined with the measured shear wave velocity profiles from the boreholes of a seabed section across the Lingdingyang Bay, the applicability of the existing empirical equations between
V
s
and depth
H
for land soils to marine soils
V
s
in the bay was examined using linear models, quadratic polynomial models, power function models, and logarithmic function models. Results indicate that the existing quadratic polynomial correlation between
V
s
and depth
H
for land soils is applicable for estimating
V
s
values of marine sandy soils (coarse sand, fine sand, fines sand) in the bay. However, none of these models are applicable for assessing
V
s
values of marine clayey soils (silty clay with sand, silty clay). The density of soil
ρ
is introduced into the equation to evaluate the
V
s
as an additional variable, the
V
s
prediction equation using two variables
ρ
and
H
is established for marine clayey soils in the bay. In the case of marine muck and mucky soils, characterized by shallow burial and soft soil, there is no significant correlation between the
V
s
and
H
. The results provide a scientific evaluation basis for determining the
V
s
values of marine soils within the bay, which is crucial for guiding project construction decisions and ensuring the safety and integrity of offshore structures in the area.
