This study discusses the importance of phreatic surface in the stability of slopes. It describes the development of phreatic layer based on Dupuit and Forcheimmer assumptions in the slope. To understand the water flow behavior through slopes, design of prototype was prepared and later the set-up was fabricated in the laboratory. The set-up includes simulated conventional dump made up of soil type material. The design of experimental set-up resembles the actual scenarios of overburden dumps constructed over the bases having inclination varying from 0 to 5°. The phreatic surfaces obtained in physical models are further compared with numerical models prepared using SEEP/W software.

土壤类型边坡潜水面的划定——物理和数值模拟的比较研究

本研究讨论了潜水面在边坡稳定性中的重要性。它描述了斜坡中基于 Dupuit 和 Forcheimmer 假设的潜水层的发展。为了了解通过斜坡的水流行为，准备了原型设计，然后在实验室中制造了该装置。该设置包括由土壤类型材料组成的模拟常规垃圾场。实验装置的设计类似于在倾斜度从 0 到 5° 变化的基地上建造的覆盖层倾卸场的实际情况。在物理模型中获得的潜水面进一步与使用 SEEP/W 软件制备的数值模型进行比较。
