| 摘 要： | 公路弃土场是一种特殊的人工堆积体，对其进行稳定性分析与评价需要掌握弃渣体的物理力学指标。文章以厦蓉高速公路水都段典型弃土场弃渣体为研究对象，介绍采用现场试验和室内试验方法，对弃渣体的最大干密度和抗剪强度等参数进行研究。通过研究得到：不同颗粒成分弃渣体的最大干密度不同，但在通常推填方式下，弃渣体的强度指标基本不受压实度控制。

| Abstract: | Road spoil ground is a special man-made accumulation, so we need to know its physical mechanics index when analyzing and evaluating its stability.Taking the typical spoil ground in Xia-Rong highway Shuidu segment as study object, the article introduces on field and indoor test and also studies the maximum dry density and shear strength of spoil disposal.The study result shows that different granular component has different maximum density.Using the normal backfilling method, the article concludes that the density index of spoil disposal basically is not controlled by compaction. |
