本文介绍pyL-1型岩石应力仪观测地应力的异常变化,分析了异常与永安地震的关系,应力长时间的大幅度连续变化可能是较大地震前兆,异常极值左右摆动是临震前兆,本人据此在去年年终会商和今年会商时提出预报意见。 相似文献

钻孔应力-应变地震前兆观测台网，是全国地震前兆监测台网的一个组成部分。该手段由于美国板块边界观测（PBO）项目的影畸，正在日益受到人们的重视（邱泽华等，2002；邱泽华等，2004a；邱泽华等，2004）。钻孔应力-应变观测对象包括：体应变、分量应变、分量应力和差应变。目前登记在册并正常运行的钻孔应力一应变地震前兆监测台站共计45个，分布于14个省、自治区和直辖市。有的台站有多种观测项目，例如昌平台，作为钻孔应力-应变综合观测台，曾经有5～6种钻孔应力-应变观测项目，目前有体应变、压容分量应变和差应变三种观测。目前正常运行的观测项目共有49个。 相似文献

试图从台站产出的原始地形变前兆数据出发,提出一些实际操作性较强的预处理方法,从已编制好的软件中给出处理实例,从而达到提高台站观测人员的科研能力,填补资料预处理方面的某些空白的目的,这对于台站人员集观测、科研于一体有着十分重要的意义。从95-01-02项目厦门地震台前兆数据预处理的实践表明:这些方法取得了明显的实效,直到今天仍然具有很大的使用价值。 相似文献

A diverse set of computer programs has been developed at the Lawrence Livermore National Laboratory (LLNL)to process geophysical data obtained from boreholes. These programs support such services as digitizing analog records, reading and processing raw data, cataloging and storing processed data, retrieving selected data for analysis, and generating data plots on several different devices. A variety of geophysical data types are accommodated, including both wireline logs and laboratory analyses of downhole samples. Many processing tasks are handled by means of a single, flexible, general-purpose, data-manipulation program. Separate programs are available for processing data from density, gravity, velocity, and epithermal neutron logs. The computer-based storage and retrieval system, which has been in operation since 1973, currently contains over 4400 data files. Most of this data was obtained from the Nevada Test Site (NTS)in conjunction with the nuclear test program. Each data file contains a single geophysical parameter as a function of depth. Automatic storage and retrieval are facilitated by the assignment of unique file names that define the storage location of each data file. Files of interest to the user may be located and retrieved by means of a search program that examines the catalog. A convention recognized by all programs in the system is that of a zero ordinate denoting a gap in an otherwise continuous data trace. This convention provides a simple mechanism for editing and displaying data files in an automated and consistent manner. 相似文献

TSP超前地质预报系统目前在我国已得到了比较广泛的应用,但厂家未提供其数据文件存储格式.为此,在举例说明TSP的应用效果后,笔者采用UltraEdit软件对多个TSP数据文件进行分析,弄清了其原始数据的总体存储结构.另外,还简单介绍了国际标准地震数据SEG-2文件的存储格式,并在Matlab语言环境下编制了读取SEG-2数据文件与TSP数据文件的程序,实现了将SEG-2文件转换成TSP数据文件的功能.因此,在今后的工作中可直接应用TSP的数据处理软件包TSPwin来处理国产的超前地震数据. 相似文献

General principles in evaluation and selection of data to be included in computer processible files intended for use in assisting regional resources appraisal are discussed against the background of activities related to file assembly at the Geological Survey of Canada. Some of the principles discussed are currently being implemented in the assembly of files at the GSC where they apply to the specific data being collected. Others are apparent from our analysis and would be applied if different data were being collected. The files currently being assembled at the Survey are intended to assist the commodity geologists in all project-related activities, one of which is regional resource appraisal. Prior to the commencement of data assembly, each data item considered for inclusion in the data files was scrutinized by members of the Economic Geology Subdivision in order to establish how it would contribute to the overall objectives of the file. At the same time strict definitions of each item were established. The main criteria applied to each data item considered for inclusion in the files were (a) the necessity of the item to satisfy the objectives of the file within the practical limitations of the resources available and (b) the general availability of the item. The characteristics found necessary to ensure integrity of the data files were (a) uniformity—the same definitions must apply to each item of similar type, (b) consistency—analytical results should be of the same method or differences noted in order that the data may be compared, and (c) mutual exclusiveness—especially when dealing with data referring to size. Such data should never be repeated in another part of the file or be included as part of another item.This paper was presented at the International Geological Correlation Program (IGCP) Project 98 entitled Standards for Computer Applications in Resource Studies held at Loen, Norway, September 27–October 1, 1976. 相似文献

This paper considers the problem of comparing the read time for a file containing an array of one-half million one-byte data
values using a direct read time with the time required to read an equivalent XML file. The XML file uses a variable-length
string encoding of the identifiers associated with each of the byte values. The XML file is about 180 times larger than the
original file of byte values. Because the XML file is much larger and because the XML parsing requires substantially more
computational work, reading the XML file on a Windows-based PC takes about 3,700 times longer than the direct read. The experimental
study shows that the XML read time increases linearly with the size of the file. Given the increased read time and the increased
probability of programming errors for the XML encoding, it appears that in cases where data archives are providing simple
binary or text files of data that may be readily understood and read with short programs, then XML may not be an optimal choice
for serving users or for preserving data. 相似文献
