1利用一些基本假定,根据太沙基一维固结理论和分层总和法的基本原理,推导出来计算分层填筑体自身沉降的公式,并编制了程序; 2建立了分层填筑高填方路堤问题的有限差分模型,并对分层填筑的施工顺序、施工速度,界面单元进行了数值模拟,获得了位移场和应力场的数值解。 - 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
用有限元法模拟分析涵洞基坑开挖时,采用分层、分步模拟开挖过程的方法,即将计算域内单元分层“挖去” ,使开挖表面成为无应力表面的方法,分析土体在卸载状态时的应力场和位移场随开挖深度的变化规律;在洞体施工后,回填土体时,据开挖完成时的应力场、位移场,通过逐级增加计算域内的单元数目,施加每级新增加单元的自重荷载,利用有限元法模拟基坑及上覆土体分层填筑的施工过程,这不仅反映土体处于再加载应力状态时,填土受力及变形的一般规律,而且这种将地基? ?涵洞? ?土体作为一个统一整体进行模拟的方法,量化了三者之间的相互作用关系。
