Associated with a project of the planned xuefengshan tunnel with 7. 6 km long during the construction of shaoyang to huaihua expressway in hunan province of shanghai to ruili national trunk highway, this paper firstly makes an introduction of the frequently - used analysis & computation methods for tunnel supporting structure. then, based on the analysis of the basic theory about the interaction mechanism of surrounding rock and support structure, a spatial computation model is made, a coupling numerical computation method with 3 - d elastic - plastic finite element and infinite element is proposed, and a comprehensive analysis has been made to the effects of the overall stability and safety of the surrounding rocks of different characteristics, different classes and under different construction methods. and thus the problem of 3 - d infinite region to which applying the general finite ca n ' t do has been resolved
6公里的雪峰山隧道工程，首先介紹了隧道支護結構的常用分析計算方法；然後通過對隧道施工過程中，洞室穩定性與支護結構相互作用機理的深入分析，建立了隧道施工過程的空間計算模型，提出了採用三維彈塑性有限元-無限元耦合的數值計算方法，綜合分析了隧道在不同圍巖特性和圍巖類別條件下，以及不同施工開挖方案等對隧道圍巖整體穩定和安全性的影響，從而解決了通用有限元方法難以解決的隧道三維無限域問題；其可充分發揮有限元法在分析非線性方面的有效性和成熟性，以及無限元法在分析處理無限域和半無限域方面的精確性和簡便性，為隧道施工過程中圍巖的穩定性分析開辟了一條新的途徑。The remote sensing imagery change detection can be categorized into three classes according to the aims of the processing : the change detection of the specific targets, such as changes of the airports, the bridges, the harbors, the missile bases etc. ; the change detection of the linear shape targets, such as changes of the roads, the airports, the buildings and the other linear targets whose outlines can be described by some lines ; the change detection of large area targets, such as the changes of the cover of some region, the development of the cities, the disaster evaluation of the floods and so on
遙感圖像變化檢測方法（簡稱變化檢測）根據處理目標要求可以分為三類：特定類目標的變化檢測，如機場、橋梁、港口、導彈基地等目標的變化檢測；線性體目標的變化檢測，如道路、機場、橋梁和一般建築物等目標的變化檢測；大面積目標的變化檢測，如某地域的植被變化、城市的發展、洪水災害評估等。本文系統地研究了基於模式識別知識檢測特定類目標、線性體目標和大面積目標變化的變化檢測方法。
