Foundation Pit Geographic Information Systems Applied Research

GIS(Geographical Information System) ,which is used in geography at first , has developed quickly in recent years . GIS is used in many fields , and it gets much profit not only to economy but also to society . The GIS of foundation pit resistance in this paper puts spatial date processing of GIS and characteristic of foundation pit resistance together. This system embodies, administrates and analyses past foundation pit timbering projects. And it offers reference to design, construction and research.The database of foundation pit resistance is established at first. The database is made up of many charts and each chart collects one kind of information that can be taken freely by the system. The GIS of foundation pit resistance is found afterward. The system, based on the foundation pit resistance database and Maplnfo software flat roof, can make all kinds of processes into reality such as spatial query or analysis of database etc. Function module can be established by the computer language of MapBasic, VB and so on, and spatial data processing can be finished in the database. In the end, the foundation pit resistance GIS of ShenZhen city can be accomplished by 100 projects datum collected from ShenZhen city.A foundation pit resistance GIS has wide foreground. It can not only make data administration time saved but also make full use of past data. We can be sure that the system exerts more and more important action with the datum continuously accumulating and system function perfecting.
