  1. In addition, the paper designs a bottom database model, selects a multi - aim strategy combining files with known data, and establishes dual interaction data model that has explicit conceptual structure and directly aims to geographic objects, and provides backing up enquiry language ( g - sql ). simultaneously, after analyzing and studying methods available for the under pipelines, the paper constructs survey adjustment calculation model, and according to the model, checks the survey of under pipelines. the results indicate that the model is suitable to actual requirement because it greatly increase calculation speed, meeting calculation accuracy requirement

    在此基礎上，對系統的底層數據模型進行設計，選擇了文件與成熟數據庫相結合的混合策略，併兼顧面向對象的數據庫（ oodb ）和可擴充數據庫（ edb ）的特點，建立了一個概念層次清晰、面向地理對象實體的雙層語義數據模型以及支持模型的查詢語言g - sql ，同時對地下管線的各種測試方法進行分析研究，建立了地下管線測量平差計算模型，並以此對所勘測的地下管線進行核算，計算結果表明，計算模型不僅大大提高了核算的速度，同時在計算精度上也符合核算的要求，是符合實際要求的關于測量平差計算的模型。
