Abstract: By means of computer simulation,in this paper,the influence of topography and the conduit structure on the earth pressure is studied,the influence of fill construction by layers is also taken into consideration.A computer program is compiled,which has the advantages of dividing the elements automatically and of simulating the topography,the conduit structure and the properties of every tier of fill.It needs less data-input and takes less computer storage.

Key words: computer simulation, conduit buried in fill, topography, conduit

摘要： 摘要本文通过电算模拟分析,研究了地形条件和管道结构对管道土压力的影响规律,并考虑了填土的分层填筑过程。本文还编制了较好的电算程序,具有自动划分单元网格,并模拟地形条件、管道结构尺寸以及每层填土性质等变化的优点,输入数据和占用计算机内存较少。
