In this paper, it is studied and analyzed characteristic of stress, distortion etc. of pipe liner structure combining dahuofang transport water tunnel practice project, tunnel boring machine construction, and it is considered that affects internal force of pipe liner for early stress of underground structure and digging load. in nonlinear finite element calculation model, folium cells have been simulated among pipe liner and pipe liner and wall rock. under varies load condition, it has educed that changing rule of stress, distortion and load characteristic pipe liner in kinds of wall rock tunnel by analysis and calculation
本文結合實際工程，分析研究了大夥房水庫輸水隧道工程在採用掘進機施工方法的情況下，利用管片襯砌的結構應力、變形等受力特性，考慮地下結構初始應力和開挖荷載對襯砌內力的影響，採用薄層單元模擬襯砌管片之間、襯砌管片與圍巖之間的非線性有限元計算模型，通過分析計算得出不同荷載工況下各類典型圍巖段隧道襯砌管片受力特徵、應力和位移變化規律。 -
The construction processes of large - scale underground structure group are very complicated. in order to quicken the construction processes, reduce price and assure success, it is necessary that adopting scientific system simulation method to simulate the whole construction processes, to make all tunnels, all activities and all machine equipment harmonious and make construction sequence schedule reasonable
大型地下洞室群施工過程是極其復雜的，採用科學的系統模擬方法對地下洞室群施工全過程進行模擬，使各洞室、工序及施工機械設備相互協調配合，使洞室群施工順序和施工進度計劃更加合理，對于加快洞室群施工進度，降低工程造價，保證工程順利進行非常必要。
