一、引言许多填地垫层系统设计时并没有考虑到垃圾堆放期间的可能失稳,这是因为设计者假定垫层系统最危险情况是在施工期,而堆放压实垃圾时能增加其稳定性。这在多数情况下是正确的,但并不是所有情况都是这样,至少有一则失稳的报道事实说明了这一点。显然,不仅 I. INTRODUCTION The design of many landfill cushion systems does not take into account possible instability during dumping. This is because the designer assumes that the most dangerous condition of the bedding system is during the construction period, and that stacking and compaction can increase its stability. Sex. This is true in most cases, but it is not the case in all cases. At least one of the reported facts of instability shows this. Obviously, not only
