The impacts of material spatial variability were usually not considered in traditional slope stability analyses. However, most geotechnical materials are usually not uniform inside a slope. Thus, traditional ways of analyses were not very reasonable. On the other hand, most geological explorations used vertical borings. Horizontal and inclined borings were seldom performed unless required by the client.

摘要 传统边坡数值稳定性分析时，大多没有考虑到材料空间变异性之影响性，材料无论在理论上或是在实际边坡上很少边坡为均质材料，因此传统的边坡分析是种较为不合理的现象，而地质钻探时都是以垂直钻探为主，除试验需要外，极少以水平或倾销钻探作为设计之基础，这也与现地所需有关系，导致空间变异性资料难以取得必需以现地资料加上文献中提及的尺度变动作为分析依据。
