In the simulation and analysis on culvert construction, the method of foundation - pit excavation layer by layer and step by step was used, i. e. the method that makes the surface of excavation have no stress, when the elements were excavated gradually in period of construction. at this process, the state of soil is unloading, the laws of stress field and displacement field with the depth of excavation were studied. based on the obtained stress field and displacement field after the excavation was completed, by using of the newly increased filling - elements " gravity and the grinding force, the simulation of the construction of body of the culvert and foundation - pit ' s filling layer by layer had also been done in this dissertation
用有限元法模擬分析涵洞基坑開挖時，採用分層、分步模擬開挖過程的方法，即將計算域內單元分層「挖去」 ，使開挖表面成為無應力表面的方法，分析土體在卸載狀態時的應力場和位移場隨開挖深度的變化規律；在洞體施工后，回填土體時，據開挖完成時的應力場、位移場，通過逐級增加計算域內的單元數目，施加每級新增加單元的自重荷載，利用有限元法模擬基坑及上覆土體分層填築的施工過程，這不僅反映土體處于再加載應力狀態時，填土受力及變形的一般規律，而且這種將地基? ?涵洞? ?土體作為一個統一整體進行模擬的方法，量化了三者之間的相互作用關系。 -
