| 6. | The evaluation of sand liquefaction is the most important content of engineering reconnaissance and the aseismatic design . so evaluating the sand liquefaction objectively and exactly is the precondition of taking preventive measures on areas where liquefaction easily occurs . it also relates closely to the safety and economic benefits of the projects
地震砂土液化评判是工程勘察和抗震设计的一项首要内容，故客观、准确地评价砂土液化，是对有可能发生液化的区域或地段进行有针对性的预防处理的前提，是关系到工程建筑的安全使用和工程建设的经济效益的重要问题。 |
| 7. | After the simple analyses with the single phased media theory , a more detailed analyses has been done , based on two phased media theory , on rayleigh wave propagation in saturated soil . the new results show that rayleigh wave will really cause larger shear stress and pore pressure than s wave in shallow layers and thus easily induce sand liquefaction
进一步，基于两相介质理论的有效应力法，研究了rayleigh波在饱水介质中的传播情况，给出了rayleigh方程，分析了饱水介质中产生的应力，并同单相介质模型的结果做了对比，证实了rayleigh波较s波可产生较大的剪应力和法向应力梯度，从而导致液化的论断。 |
