The analysis of seismograms indicates that the first arrival is a p - wave , followed by a s - wave 地震波记录曲线的分析表明,初至波是p波,随后是s波。
By using the attenuation property of the rayleigh surface wave to invert the quality factor of crust and upper mantle , this paper yields the s - wave quality factor 3d structure of crust and upper mantle of china , and the viscidity structure of this area as well 本文主要通过rayleigh面波衰减反演地壳上地幔s波品质因子q _ ,建立了中国大陆地壳上地幔s波品质因子全三维结构。探讨了中国大陆区域地球内部粘弹性结构。
The initial model ( vs , vp , qb , p ) based on previous work of this research group is adopted , and by terms of the relationship between the attenuation factor and s - wave quality factor , the stochastic least square is conducted to inverse the o > > of ail layers under every grid , i . e . the qb structure of every uiut - column Q _ 、 p ) ,利用衰减系数和层内s波品质因子q _之间的关系,通过阻尼最小二乘法反演方法反演每个单元格内各层q _ ,得到每个“单元柱”的q _三维结构
This is of very important significance to understand the material property and geodynamic of corresponding area , , the surface wave attenuation mechanism and the inversion algorithm of attenuation and s - wave quality factor are discussed systemically in this paper . some important fruits and understanding are resulted from the the crust and upper mantle tomography of china . ( 1 ) calculating of the rayleigh surface wave attenuation factor y 本文首先探讨了面波衰减的机理,对面波衰减和s波品质因子q _反演的计算方法进行了系统的研究,并对中国大陆地区地壳上地幔q _三维结构进行层析成像,取得了以下重要成果: ( 1 ) rayleigh面波衰减系数计算。
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。
The methods were realized directly inversion of the possion ' s ratio from cdp gather and gas - bearing identify . by applied the late theory of avo technology , after inputting the p wave section and s wave section , the p wave and s wave impedance were obtained by applying simulate anneal inversion and used the log as a constrain condition , eventually , obtain the elastic parameter u and x by p and s impedance . then , the gas - bearing will be identified by u and x . by applying this method , the avo combination inversion of prestack and post were realized 利用上述的反演方法实现了泊松比从道集的直接反演,利用加权叠加技术实现了含油气的识别,并利用当今avo研究的最新成果,以加权叠加技术分离出的p波和s波剖面作为输入,在测井的约束下,采用模拟退火方法分别进行p波和s波波阻抗反演,通过p波和s波波阻抗来求取弹性参数和,再通过和的联合解释来进行含油气的判别,实现了avo的叠前叠后的联合反演。
