The Lueyang-Zhongba Section of Baoji-Chengdu Railway and the Hujiaying-Chongqing Section of Xiangfan-Chongqing Railway are both in floded mountain area and crossing both the Qingling Geosyncline and Yangzi Platform as major geotectomic units (Fig. 1). Since open to traffic, a number of geological hazards have occured,Some siting principles for railway in mountainous area of geosyncline are as follow: 1) Fewer deep excavation and, if inevitable, stabilize them with reliable supports, 2) More crossings over the river to utilize terraces for evading geo-hazards, 3) A long tunnel will be superior to compact tunnels and 4) Long tunnel is suitable for an area of large or dense geo- hazards.Besides, a railway in mountainous area is in most cases an abank line in the river valley stretching partly or entirely along an active fault or a belt of active faults, where crushed stones spread widely and tattered rocks are less cemented, therefore debrisflows are main disasters which raise river beds constantly or abruptly. Considerations for siting railway in an active fault valley with numerous debrisflow ravines seem to be: 1) Bridge over debrisflow ravine at suitable point of transportation zone if the line is sufficiently elevated, 2) Tunnel of chuteplus - tube of detou via opposite bank for insufficient elevations and 3) No cut even cut -and -fill in deposition zone will be permitted in any case until the debrisflow is proved no more development.

Based on the data of the river system orientation,structure joint form and the P axis direction of seismic fault plane,the crustal stress distribution in the area is studied.The stress orientations can be summarized from NW to SE:NE26° in west Gansu,NE36° in middil Gansu,NE54° in east Gansu,and SE98° in south Gansu.The relations between modern structure stress field and earthquake,landslide and debris flow in the area are also discussed in the paper.The research shows that that natural geohazards are not just...

Based on the data of the river system orientation,structure joint form and the P axis direction of seismic fault plane,the crustal stress distribution in the area is studied.The stress orientations can be summarized from NW to SE:NE26° in west Gansu,NE36° in middil Gansu,NE54° in east Gansu,and SE98° in south Gansu.The relations between modern structure stress field and earthquake,landslide and debris flow in the area are also discussed in the paper.The research shows that that natural geohazards are not just related to the action of external forces but to that of the internal ones,and that the spatially distributed structure of the different erosion and gravitational geological actions of external forces is controlled by geostress.The interaction between Indian and Eurasian plates is the mais cause of the crustal stress distribution and natural geo hazards in the area of Gansu.

There are two branches of spatial information technology: one is related to spatial mapping for which the tool is GIS, the other is related to numerical data processing for which the tool is geostatistics. These two spatial techniques can be connected with each other to solve most of the spatially defined geoscientific problems. The kernel of GIS is to establish topology of mapping elements and relationship between spatial and attributive information. It is based on these two important points that make it possible to compile, retrieve and display many and varied mapping and corresponding information of geosciences flexibly and efficiently. In comparison with all of the other existing applied computer systems in geosciences, GIS is thought the most suitable and attractive one. Geostatistics is a technique processing spatial data which is, in fact, a spatial version of traditional statistics. It is noted that there is a critical problem for applications of traditional statistics, including multivariate statistics, in geosciences because traditional statistics ignores spatiality of variables which is a strong nature of geoscientific processes. Geostatistics is developed based on spatiality of variables so that it is suitable for geosciences. As transformation can be made between mapping and numerical information, two spatial information techniques have intrinsic relationship. Using both GIS and geostatistics enable geoscientists to access and process spatial information in both states, mapping and numerical. Spatial information technology provides sophisticated and powerful approaches to mineral resources appraisal, geophysical, geochemical and remote sensing data processing, geo environment and geo hazard assessment, and so on. Spatial information technology is specially suited to geosciences. It not only can be used to increase the efficiency of geoscientific mapping and data processing, but also would change the concepts on maps of geosciences that would exerts an extensive influence on various fields of geosciences.

空间信息技术有两个分支:其一是空间图形信息技术,即地理信息系统(GIS);其二是地质统计学。两种技术在本质上是相通的。GIS的核心是建立图形元素的拓扑关系与建立空间数据库与属性数据库的联动关系。正是立足于这两个重要关系,使对千变万化的地学图形信息进行灵活高效的编辑、检索与显示成为可能。在迄今为止所有的计算机应用系统中,GIS无疑将在地学中产生最重要的影响。地质统计学是一种空间数字处理技术,它是传统统计学的空间版本。用包含多元统计学的传统统计方法研究地质问题存在严重的缺陷,因为传统统计学忽略变量的空间存在,而地质过程具有强烈的空间性。地质统计学恰恰是立足于变量的空间关系发展起来的统计科学,因此它特别适用于地球科学。正如空间图形与空间数字可以相互转换一样,两种空间信息技术也存在内在的关系。利用GIS与地质统计学这两种空间信息技术,使我们能不断地在空间图形与空间数字这两种状态间穿越。空间信息技术为地质学家在进行矿产资源预测、物化遥数据分析、地质环境评价、地质灾害评价与矿产资源管理等方面提供了强有力的工具。空间信息技术特别适合于地球科学,它不仅能大幅度地提高地球科学对图形的编制和研究的效率和水平,而且也将转变传统的?
