Piping erosion, and debris flow travel distance

地下水渗漏可能导致土壤骨架更细颗粒的内部侵蚀。如果继续不加控制，内部侵蚀将导致大量的细粉损失。这可能会影响土壤的强度，使其变得更弱，偶尔容易发生局部坍塌。这种现象在某些山坡土壤中自然发生。用压实的山坡土壤建造的土坝也被发现容易受到内部侵蚀。对大型水坝的性能进行例行监测，以确保其安全。适当了解被认为易受影响的土壤内部侵蚀的可能性，有助于在土坝的长期使用寿命期间对其进行监测和运行。它可以帮助工程师完全自信地解释性能数据，并相应地分配维护预算。拟议中的研究探讨了内部侵蚀的基本原理，以及与土壤强度损失的联系。

Groundwater seepage can lead to internal erosion of the finer grains of a soil skeleton. If it continues unchecked, the internal erosion will result in a significant loss of fines. This can affect the strength of the soil, leaving it weaker and, occasionally, susceptible to a localised collapse. The phenomenon occurs naturally in some hillslope soils. Earth dams, built from compacted hillslope soils, have also been found susceptible to internal erosion. The performance of large dams is routinely monitored, to ensure their safety. A proper understanding of the potential for internal erosion, in soils that are deemed susceptible, complements the monitoring and operation of earth dams, over their long service life. It assists engineers in interpreting the performance data with complete confidence, and allocate maintenance budgets accordingly. The proposed research examines the fundamentals of internal erosion, and the linkage to loss of soil strength.
