Piping erosion, and debris flow travel distance

地下水渗漏会导致土壤骨架的细小颗粒受到内部侵蚀。如果继续不加控制，内部侵蚀将导致重大罚款损失。这可能会影响土壤的强度，使其变得更弱，有时还容易发生局部坍塌。这种现象在一些山坡土壤中是自然发生的。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。大型水坝的运行情况受到例行监测，以确保它们的安全。在被认为是易受影响的土壤中，正确了解内部侵蚀的可能性，是对土坝长期使用寿命的监测和运行的补充。它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。这项拟议的研究考察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.
