摘　　要：研究降雨渗流对靠崖窑土体结构的影响,运用有限差分数值软件FLAC3D对台梯型5孔一列半圆拱靠崖窑进行了应力场—渗流场耦合的有限差分数值模拟计算,通过孔隙水压力、垂直位移和塑性区的结果表明,在降雨渗流条件下,加强下台梯窑洞的稳定性是最关键的环节。In order to research the rainfall seepage＇ influence on the kiln soil structure, the author uses powerful finite dif- ference numerical software FLAC3D and nested FISH language and computer VC＋＋ high-level programming languages, and the finite difference numerical simulation of seepage field-coupling stress field has been made towards the cliff kiln of a list of semicircle arch of ladder model five holes, the results of the pore water pressure, vertical displacement and plastic zone has showed that, in rainfall seepage condition, to strengthen the stability of the down-ladder caves is the key conclusions.
