简介:Common-reflection-point(CRP)集合是连接地震数据和petrophysical参数的一座桥。预先叠属性抽取并且预先叠倒置,他们俩是水库预言的重要工具。CRP集合的质量通常在地震探索的精确性上有大影响。因此,预先叠CRP集合噪音抑制技术成为一个主要研究方向。基于向量分解原则,这里,我们建议一个方法压制噪音。这个方法由在各种各样的方向寻找估计最佳的单位向量然后通过向量角度变光滑和限制压制噪音。模型测试显示建议方法能把有效信号与噪音分开很好并且在单个wavenumber大小写中有效地压制随机的噪音。我们到真实数据的方法的申请证明方法能恢复有效信号,好振幅保存了从预先叠甚至在到噪音比率(SNR)的低信号的情况中的吵闹的地震数据。
简介:过去常在在当前的地震代码采用的基于力量的设计过程决定力量减小因素的最重要的参数是结构的韧性。为在一个灵活基础上支持的结构,韧性因素能被基础依从影响。在当前的代码给的韧性因素主要被分配忽略这研究的目的是在像栈的结构的韧性因素上估计SSI现象的意义的SSI并且因此的效果。像栈的结构的使变形的配置就非线性的时刻弯曲关系而言作为横梁元素的一个集合被理想化,当一个线性摇摇摆的模型被实现为支持的土壤建模时。用一套人工的记录,重复了线性、非线性的分析被逐渐地在非线性的分析增加加速的紧张到首先在线性、非线性的分析钢让步被观察的水平和相应于栈倒塌的水平执行。无弹性、有弹性的电阻之间的差别以排水量韧性因素被确定了。结果显示基础灵活性能减少系统的韧性并且忽视这现象可以在灵活地支持的R/C像栈的结构的地震表演的预言导致错误的结论。
简介:改进集中的能力预先叠时间移植允许想象的节反映结构的特征,深度,和接口形状,它是为起始的深度迁居速度模型的准备的关键步。传统的对称的旅行时间方程基于一个分层的模型的假设被导出。完成与强壮的侧面的变化集中在媒介的需要的效果是困难的。非对称的旅行时间方程基于谎言代数学和一个伪differential操作符包含能甚至在强烈侧面的可变媒介并且也改进集中的能力的侧面的速度衍生物为相对振幅保藏的重量系数的计算精确。与对称的方法相比,非对称的方法是更有效的。在这篇论文,我们描述几关键步非对称预先叠旅行时间计算和现在的一些测试用合成、真实的数据结果。
