SGER: Bamboo for Soil Slope Reinforcement

马里兰大学cbet -0742154 sger：竹子作为土壤边坡加固竹子被认为是世界上生长最快的植物。最近，西方在选择建筑材料时对自然资源的明智利用的关注重新引起了人们对竹子的关注，因为竹子是一种未充分利用的、可自我补充的建筑材料。在这一点上，本研究的主要重点是在短期边坡稳定中使用竹子，使用竹子进行土钉支护。扩展到其他类型的土壤加固应用的潜力仍然是开放的。在土体加固中，土体受力低且不集中，不存在缩胀问题；事实上，含水量的增加甚至可以提高竹子的抗拉强度。这些方面表明竹子可能是一种很有前途的土壤加固材料。目前还没有检验竹子的标准。这项工作将侧重于探索基础知识，包括：-测量竹子与土壤（沙子，淤泥和粘土）之间的摩擦，使用简单的拉出测试。-测量剪切面被竹子穿过时对土壤剪切的阻力。-测定试验中所用竹子的抗压和抗拉强度。预计这项研究将产生各种更广泛的影响。首先，竹材加固的最终应用将是稳定临时的，否则不稳定的挖掘，或在紧急情况下，提供短期稳定时至关重要的控制，或修复，边坡破坏。虽然这项研究可以应用于低技术的西方建筑条件，但目前它的主要应用预计将在发展中国家；联合国、（美国）国家工程院和世界银行指出，减灾是全球减贫议程的一个关键组成部分。其次，可持续性必须成为工程开发的基本概念；这项研究将有助于了解增加使用竹子的潜力的具体情况，并增加工程内部的运动，根据可持续性重新评估建筑材料的选择。第三，研究团队将包括一名本科生研究员，这是一项在学生从本科生过渡到研究生学习中发现的宝贵技术。第四，有希望的结果可以通过三种传统途径传播：作为工程杂志的技术说明；作为在适当会议上提出的文件，例如关于环境可持续性的文件；并在一年一度的全国工程师无国界会议上发表演讲。第五，这项研究有可能付诸实践：如果结果支持其可行性，那么通过马里兰大学的无国界工程师项目，就有机会在实地测试该技术。

Goodings, Deborah, PIUniversity of MarylandCBET-0742154SGER: Bamboo as a Soil Slope ReinforcementBamboo is reputed to be the fastest growing plant in the world. Relatively recent concerns in the West regarding wise use of natural resources in choices for building materials has rekindled attention to bamboo as an underutilized, self-replenishing building material. The principal focus of this research, at this point, is on use of bamboo in short term slope stabilization, using the bamboo for soil nailing. Potential for extension to other types of soil reinforcement applications remains open. In soil reinforcement, stresses on the reinforcement are low and not concentrated, and shrinking and swelling is not a problem for soil reinforcement; in fact, an increase in water content may even increase the tensile strength in bamboo8. These aspects suggest that bamboo may be a promising candidate as a soil reinforcement material. Standards in testing bamboo do not exist. This work will focus on to exploring the basics, including:- measuring the friction between bamboo and soil (sand, silt, and clay) using simplepullout tests.- measuring the resistance to soil shearing when the shearing surface is crossed by bamboo.- measuring the compressive and tensile strengths of the bamboo used in these tests.Various broader impacts are expected from this research. First, the ultimate application for bamboo reinforcement will be to stabilize temporary, otherwise unstable excavations, or in emergency conditions, to provide when short term slope stabilization critical to control, or to remediate, slope failure. While this research could be applied to low tech Western building conditions, its primary application at this point, is expected to be in developing countries; the United Nations, the (US) National Academy of Engineering, and the World Bank note that disaster reduction is a critical component of the global poverty reduction agenda. Second, sustainability must be an underlying concept in engineering development; this research will contribute both to the specifics of understanding potential for increased uses of bamboo, as well as adding to the movement within engineering to reassess choice of building materials in light of sustainability. Third, an undergraduate researcher will be included in the research team, a technique found invaluable in transitioning students from undergraduate to graduate study. Fourth, promising results can be disseminated through three traditional avenues: as a technical note in an engineering journal; as a paper presented at an appropriate conference, on, for example, environmental sustainability; and as a presentation at the national, annual Engineers Without Borders conference. Fifth, this research has the potential to move into practice: opportunities to test the technique in the field exist through the Engineers Without Borders projects of the University of Maryland, if results support its viability.
