摘要:
给出基于一维比奥固结理论的粉质土海床波致累积液化的简化计算方法.以黄河口埕岛海域海床为例,通过动三轴试验测试粉土孔压增长状况,回归得到孔压增长参数a=0.613,b=0.185.通过计算表明,埕岛海域粉质土海床水深7~8 m处,海床液化深度最大,在50 a一遇的波浪荷载作用下,液化深度达到5.2 m,这与该区地质灾害扰动深度和地质灾害在此水深处相对集中相对应.
Abstract:
One simplified silt seabed liquefaction calculation method induced by wave based on Biot one dimensional consolidation theory was put forward. Taking the Chengdao seabed at the Yellow River estuary as an example, the pore pressure growth of silt were measured in the dynamic triaxial tests, and the growing parameters a=0.613, b=0.185 were gotten. The calculation shows that the seabed liquefaction depth is maximum at the water depth 7-8 m, and under the wave loads with a recurrence period of 50 years, the liquefaction depth reaches 5.2 m, which corresponds with the geological disaster disturbed depth and the water depth of concentrated distributed geological disasters.
