工程土壤中边坡的崩塌是由多种因素造成,包括边坡几何、材料强度、水文和地下水、季节性气候变化以及植被和野生生物的影响。可以预料,气候变化引起的降雨方式改变将使问题更加严重。修复方法的选择依赖于现场条件、物流和成本,可包括征用额外的土地、减小坡度、安装额外的排水设施(如扶壁或水平排水渠)、布设土钉、及通过结构法提高稳定性。上述所有方法都有其局限性,且其中一些方法成本非常高。另一种选择是采用电动技术,即采用导电的土工合成材料。本技术说明旨在介绍电动土工合成材料(EKG)的概念,并说明如何将该技术用于现场边坡加固和修复,以及该技术与其他方法相比,如何降低成本及碳足迹。
Slope collapse in engineering soils is caused by a number of factors, including slope geometry, material strength, hydrology and groundwater, seasonal climate change, and the effects of vegetation and wildlife. It can be expected that the change in rainfall patterns caused by climate change will exacerbate the problem. The choice of remediation method will depend on site conditions, logistics and costs and may include expropriation of additional land, reduction of grade, installation of additional drainage facilities such as buttresses or horizontal drains, soil nailing and stability improvements through structural methods . All of the above methods have their limitations, and some of them are very costly. Another option is the use of electric technology, that is, the use of conductive geosynthetics. This technical note is intended to introduce the concept of electric geosynthetics (EKG) and explain how it can be used for on-site slope reinforcement and repair, and how the technology reduces costs and carbon footprint compared to other approaches.
