中文摘要
该项目的目的是提高沙质海岸斜坡对地表侵蚀和浅层滑动或崩塌的抵抗力,这既是由于地面上形成的压缩增加了有效应力,也是由于嵌入的活茎和插穗周围纤维根的形成增加了表观粘聚力。将调查结合土壤生物工程措施的有效性,如活桩和束与锚网系统。将进行分析研究,以确定网和土工布的最佳锚固系统,该系统除了考虑网的粘弹性性质和拉伸形状外,还考虑了锚杆的几何布置、间距、长度和倾角。
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.
