中文摘要
该项目的目标是增加对地表侵蚀和浅层滑动或海岸沙质斜坡的抵抗能力,这是由于地面上的压缩增加了有效应力,以及嵌入的活茎和岩屑周围纤维根发育增加了明显的凝聚力。将研究将土壤生物工程措施(如活体桩和锚固网)与锚固网系统相结合的有效性。将进行分析研究,以确定网架和土工织物的最佳锚固系统,该系统将考虑锚杆的几何排列、间距、长度和倾角,以及网架的粘弹性和拉伸形状。
英文摘要
The objective of this project is to increase the resistance to surficial erosion and to shallow sliding or sloughing in sandy coastal slopes as a result of both increased effective stress from developed compression on the ground surface and by an increase in apparent cohesion from fibrous root development around imbedded live stems and cuttings. The effectiveness of combining soil bioengineering measures such as live staking and fascines with anchored netting systems will be investigated. Analytical studies will be carried out to determine the optimal anchorage system for netting and geofabrics that takes into account the geometric arrangement, spacing, length, and inclination of the anchors in addition to the visco-elastic properties and stretched shape of the netting.
