查询词典 seismic

Firstly, we introduce the technology of seismic geometric attribute for fault identification detailedly at home and abroad. Secondly we study the coherence, texture,curvature attribute and tricolor display technology of RGB to identify fault; In the part of coherence,we compare the traditional algorithms with model and actual data,mainly study the geometric structural tensor and wavelet multi-scale sub-frequency coherent algorithm; In the part of texture attribute, we introduce texture energy, texture contrast, texture entropy and texture homogeneity attribute.By merging texture attributes of different directions,the effect are more clear; In the part of curvature attribute,we study and analyze fractional-order curvature attribute's extraction and its application in fault identification; The RGB display technology mainly introduces how to merge multi-attributes in order to getting more richer and more clearer information.

首先具体先容了地震几何属性识别断层技术的国内外研究现状；然后分别研究了相干属性、纹理属性、曲率属性和RGB三原色显示技术来识别断层；其中相干属性通过模型和实际资料对传统相干体算法进行了对比，重点研究了几何结构张量相干体算法和小波多标准分频相干体算法；纹理属性主要先容了纹理能量、纹理对比、纹理熵和纹理一致性属性，通过对不同方向的纹理属性进行融合，效果更清楚；曲率属性重点分析了分波数曲率属性提取及其在断层识别中的应用；RGB三原色显示技术则主要先容了如何进行多属性融合来或得更丰富、清楚的信息，在此基础上开发了基于。

The trend of denudation was analyzed. The tectonic framework of Tazhong area presented as"west-east differentiation and north-south dissimilitude". Based on the seismic profile, the major pattern of the faults was thrust fault with high angles and involved in base, and the main thrust faults developed back to back companion faults, which formed flower structure.

The friction energy dissipator is a seismic response damping device with simple structure and easy installation.

周云摩擦耗能器是一种构造简单、制作方便的耗能减震装置。

The 1-4 order variation law of frequency, energy and distance of MS events before destabilizing can display the change rule of MS events. According to the variation law of the difference of frequency, energy and distance of micro seismic events before destabilizing, the fracture of rock mass can be precisely predicted. This is of great importance for safety of colliery.

微地震事件的距离、能量、频数的一到四阶差分均能够显示微地震事件的变化规律，根据未失稳岩体微震事件距离、频数、能量差分变化规律，能够准确地利用微震监测技术预报岩体破裂，这对于采用微地震监测技术解决矿山井下岩体破坏失稳预报具有重要指导意义。

This paper has analysed a great many of problems, such as the spatial distribution law of the earthquake and the move of the seismic source.

In this dissertation, certain problem relating to dynamic property and seismic response behavior of one certain cable-stayed bridge are studied with ANsYs, with 141+345+141m span, double tower and double cable plane.

利用大型有限元程序Ansys，对跨度组合为141+345+141m的双塔双索面混凝土斜拉桥进行动力特性和地震反应的分析。

Fault zone is very clear in not only geophysical field but also seismic section, and it controls the development and distribution of sedimentary facies. On its downthrow, extension-depression basin develops, and on the upthrow, neritic carbonate platform or isolated carbonate platform develops, it is the structure--paleo-geography boundary of the two kinds.

断裂带在地球物理场和地震剖面上均有明显显示；并且控制了沉积岩相的发育、分布，表现为在该断裂北侧下降盘形成伸展裂陷盆地，上升盘一侧发育浅海碳酸盐台地或孤立碳酸盐台地，断裂带构成二者的构造-古地理边界。

The results show that the bedrock moves 8 m en masse when the epicenter is located near the railway,while the Quaternary loose sediments and groundsill are deformed.The horizontal diaplacement of the Quaternary close to the fault is obviously smaller from above downward,while the rails and groundsill show successive left-lateral crooked deformation for about 25 m.There occur a NE-trending tensional graben and a NW-trending seismic drumlin on the east and west sides of the railway respectively.

结果表明，震中位于铁路线附近时，基岩整体移动，而第四纪松散层和道床则发生了变形，靠近断裂带附近的第四系自下而上水平位移明显减小，而铁轨和道床没有明显的断错，表现为长度约为25m的连续左旋弯曲变形；在铁路东、西两侧形成NE向的张裂陷和NW向的地震鼓包。
