Researching & Application Of Harbin City Geotechnical Engineering Information System

Today, more recognition has been concentrated on the research and teaching of geographic information system (GIS). Urban information system (UIS) is special geographic information system; it is the dimensional type information system serve for city construction, city planning, and city management, which could provide information and information service.In this paper, we introduce the special information system ------ the Geotechnical Engineering Information System mainly. It is important part of Geographic Information System; it is relation to every tache of geotechnical inspection flow, from gathering information, inspect design (engineering planning), field testing, earth swatch experiment to clean up inner information and . computer drawing. The system is very meaningful to the research of city construction program feasibility project, choosing program location, ground evaluate, the research of city geological construction distribution, city defend and reduce disaster. It could provide dependable evidence for government plan the project of city construction; enhancing the forecast ability of economic construction.We have unified the standard layer partition rule, deal with the standard processing according to different physiognomy unit, stratum cause of formation, age, lithology and engineering feature.In the design,The Value of exert its all data information,We must build a kind of big and nimble's data room store data,then the computer complete calculate data.The show a kind of new works means of graph and script illustration.It can insteadof research of feasibility project and field work of initial investigation stage.The theory of system dependable introduce geotechical engineering calculate usually calculate model and calculate theory.include soil supposing. saturation soil permeate soild theory.destroy theory. sub grade bearing capacity and soil pressure calculate theory.This paper emphasize introduce the partition of standard ground layer, the research means the construction of database has become possible, we have got strong guarantee for the construction of information system. The events drive way explore practical program.In the process of study, we get the enthusiastic support of Harbin city special technical personnel and experts.
