All over the world, the coastal community faces the problem of coastal erosion, either short stability and method of construction of reefs are the physical 网页2017年6月1日 1. Introduction. Artificial vegetation restoration is one of the most common and effective ways to restore sand dunes and improve the ecological environment in many desertification regions of the world (Durán and Herrmann, 2006, Ffolliott et al., 1995, Li, 2014, Wang et al., 2013, Yong et al., 2005).The artificial vegetation system exerts 网页An ever-growing population and a continuing trend towards urbanisation mean that around 40 billion tonnes of sand are mined each year to meet the world’s increasing demand for construction materials. Because sand from the desert is unsuitable as a building material, it must be mined or dredged from rivers, deltas, and coastal and marine ecosystems, 网页根据国标规定，凡经除土处理的机制砂、混合砂都统称为人工砂。机制砂是由机械破碎、筛分制砀，粒径小于4.75mm的岩石颗粒，但不包括软质岩，风化岩石的颗粒，混合砂是由 网页2000年1月1日 Download Citation ARTIFICIALLY NOURISHED AND CONSTRUCTED BEACHES Construction, improvement and maintenance of beaches through the artificial deposition of sand on the shore is rapidly gaining 网页2023年2月3日 Shore nourishments are projects where the coastal system is fed with sediments (sand) from a source (borrow area) at a sufficient distance from the project area 网页The range of stable slopes (nf1) are 3 ≤n ≤ 12. It was observed that the sand particles at the lower part of the slope are transported upward and deposited at a CS.1 higher part of the slope and vice versa. Experimental result showed the stability of beach profile with the CS.2 utilization of bar as well as berm. 网页2020年3月7日 The undrained (say constant volume) behavior of granular soils is conventionally divided into three categories (see Fig. 5): (a) non-flow in which sand specimen in dense state demonstrates continuous strain hardening up to the critical state; (b) limited flow instability wherein sand specimen in medium loose state demonstrates a 网页However, many problems have arisen in practice, such as large areas of artificial sand-binding vegetation degrading over the decades. Therefore, how to maintain the stability of sand-binding vegetation in ecological restoration 网页2021年1月22日 (1) Wind-carried sands trapped around the traffic lines: The construction of railways and highways will cause a drop in wind speed, which decreases the sand-carrying capacity of the winds and their ability to transport airborne sands, thereby resulting in sands being deposited on the downwind side of the built obstacles. Traffic lines may become 网页This report provides a detailed review of Artificial Ground Freezing (AGF) as a technique to improve site conditions for civil engineering projects. Da Re et al. 2003 performed 网页An ever-growing population and a continuing trend towards urbanisation mean that around 40 billion tonnes of sand are mined each year to meet the world’s increasing demand for construction materials. Because sand from the desert is unsuitable as a building material, it must be mined or dredged from rivers, deltas, and coastal and marine ecosystems, 网页2022年11月8日 Results of some constant shear-drained (CSD) tests conducted on both loose and dense sand are presented. Using the critical state line and a modified state parameter, a new framework for analysing the instability of granular soil slopes is proposed. The test data were examined and interpreted using the new framework. Instability lines 网页2020年10月27日 During SLR, waves can access onshore sand supplies, thus ensuring continued healthy beaches. a,b, The arid Namibian coast with its bare sand (a) and the subtropical KwaZulu-Natal coast (b) with 网页根据国标规定，凡经除土处理的机制砂、混合砂都统称为人工砂。机制砂是由机械破碎、筛分制砀，粒径小于4.75mm的岩石颗粒，但不包括软质岩，风化岩石的颗粒，混合砂是由 网页2000年1月1日 Download Citation ARTIFICIALLY NOURISHED AND CONSTRUCTED BEACHES Construction, improvement and maintenance of beaches through the artificial deposition of sand on the shore is rapidly gaining 网页2021年4月21日 Underwater experiments have shown that, as soon as the flow is strong enough to transport grains, a flat sand bed destabilizes into periodic bedforms
