The results indicated that the vertical concentrations of COD and DO has sharp stratification profiles in the mixing region of salt and fresh water.
1999年夏季对珠江口伶仃洋的COD、DO、盐度、温度等项目进行大规模的调研 ,结果表明 :在伶仃洋咸淡水交界海域 ,COD、DO垂向层化现象明显 ,根据其层次结构可分为上中高下低型、上高中下低型、上下高中低型。
Simulating on soft soil embankment solidified drainage and settlement with or without shallow solidified layer under the application of plane strain conditions embankment load,three-dimensional numerical simulating on roadbed and embankment deformation with vehicles on the road,the results indicate that shallow solidified soil layer changes the stress distribution of the ground,and reduces .
采用现场孔隙水压力静力触探(CPTU)对长江河漫滩相典型非均质性天然沉积软土层进行原位试验,通过对平面应变条件路堤荷载作用下有无浅层固化层的软土地基固结排水与沉降进行仿真模拟,对路面车辆重载作用下有无浅层固化层的路基及基底变形进行三维数值仿真,结果表明:地基浅层固化层的设置改变了地基应力场的分布,通过应力扩散作用减小了地基土体的附加应力进而减小了地基土体的沉降量,基底固化层通过增强路基基底的刚度来增强路基的整体刚度,减小了路基的变形,提高了路基的整体稳定性。
