A new scour countermeasure using solidified slurry for offshore foundation has been proposed *** solidified slurry is pumped to seabed area around foundation for scour protection or pumped into the developed scour holes for scour repair as the fluidized material solidifies *** the pumping operation and solidification,the engineering behaviors of solidified slurry require to be considered synthetically for the reliable application in scour repair and protection of ocean engineering such as the pumpability related flow value,flow diffusion behavior related rheological property,anti-scour performance related retention rate in solidification and bearing capacity related strength property after *** this study,a series of laboratory tests are conducted to investigate the effects of mix proportion(initial water content and binder content)on the flow value,rheological properties,density,retention rate of solidified slurry and unconfined compressive strength(UCS).The results reveal that the flow value increases with the water content and decreases with the binder *** the solidified slurry exhibits Bingham plastic behavior when the shear rate is larger than 5 s^(-1).The Bingham model has been employed to fit the rheology test results,and empirical formulas for obtaining the density,yield stress and viscosity are established,providing scientific support for the numerical assessment of flow and diffusion of solidified *** rate of solidified slurry decreases with the water flow velocity and flow value,which means the pumpability of solidified slurry is contrary to anti-scour *** unconfined compressive strength after solidification reduces as the water content increases and binder content decreases.A design and application procedure of solidified soil for scour repair and protection is also proposed for engineering reference.

提出了一种新型对偶复合左右手传输线(Dual Composite Right/Left-handed Transmission Line,D-CRLHTL)结构,该结构单元由T型缺陷地(T-shaped defected ground structure,T-DGS)结构以及矩形贴片短截线组成,基于对传输线单元结构传输特性的全波仿真分析,设计了一款带阻滤波器。由于利用了基于T-DGS的D-CRLH传输线,该带阻滤波器具有较小的尺寸和更加陡峭的边沿特性。实验结果和仿真设计结果吻合较好:阻带中心频率为4.15GHz,插入损耗为30dB,3dB带宽为1.9GHz,20dB带宽为1.55GHz。
