| 摘 要： | 通过一系列野外及实验室试验，对澳门地区土层地震波速进行了初步测量，从初步的现场试验结果来看，浅层的地震波速受到堆填物料的影响颇大，变化显得较为宽广，随着深度的增加，由于天然土层较为均一，地震波速的变化亦见收窄，现场剪切波速数据与标准贯人试验（SPT）数据可见一定吻合性。而通过等向及异向固结的实验室试验，发现澳门海泥的剪切波速在同一平均有效应力而不同应力路径下大致相同，此外，比较野外及实验室试验结果，亦显示澳门海泥的剪切波速受土体天然结构影响不大。

| Abstract: | A series of in-situ tests and laboratory tests have been carried out to investigate seismic wave velocities and soil properties of Macau strata. The preliminary field testing results show that seismic wave velocities from shallow layers are significantly influenced by fill materials at the ground surface. Large dispersion of wave velocities was observed in the measurements. As the depth increases, the variation of measured wave velocities becomes smaller. SPT values and shear wave velocities were found fairly correlated. The results from isotropic and anisotropic consolidation tests demonstrate that the shear wave velocities are rather similar under deferent stress paths. In addition, comparison of the results from field and laboratory tests shows that the shear wave velocities of Macau marine clay seem to be not significantly influenced by its natural soil fabric. |
