针对唐山曹妃甸地区滨海软土地区正在进行的海上风电工程,通过GDS动三轴试验模拟波浪循环荷载,对滨海软土的动模量和阻尼比进行了试验研究,探讨了动应力幅值和围压对它们的影响。研究表明:滨海软土的动模量和阻尼比随动应力幅值、围压的增大而增大;并得出了滨海软土的最大动剪切模量,可供分析唐山曹妃甸地区滨海软土一般动力特性,为其他进一步研究提供理论参考。
Aiming at the ongoing offshore wind power project in the coastal soft soil area of Caofeidian area in Tangshan, the dynamic modulus and damping ratio of the coastal soft soil are studied by GDS dynamic triaxial test simulating the cyclic loading of the wave. The dynamic stress amplitude and the surrounding area Impact on them. The results show that: the dynamic modulus and damping ratio of coastal soft soil increase with the increase of dynamic stress amplitude and confining pressure; and the maximum dynamic shear modulus of coastal soft soil is obtained, which can be used for the analysis of the coastal area of Caofeidian in Tangshan The general dynamic characteristics of soft soil provide theoretical reference for other further research.
