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.

Goodings，Deborah，马里兰大学，CBET-0742154 SGER：竹子作为土壤边坡加固材料竹子被认为是世界上生长最快的植物。在西方，人们最近对明智地利用自然资源来选择建筑材料的关注，重新引起了人们对竹子作为一种未充分利用的、自我补充的建筑材料的关注。在这一点上，本研究的主要重点是使用竹子在短期边坡稳定，使用竹土钉。扩展到其他类型的土壤加固应用的潜力仍然是开放的。在土壤加固中，钢筋上的应力很低，不集中，收缩和膨胀对土壤加固来说不是问题;事实上，含水量的增加甚至可以增加竹子的抗拉强度8。这些方面表明，竹子可能是一个有前途的候选人作为土壤加固材料。测试竹子的标准并不存在。这项工作将侧重于探索基础知识，包括：-使用简单的拉力测试来测量竹子和土壤（沙子，淤泥和粘土）之间的摩擦力。当剪切表面被竹子穿过时，测量土壤剪切阻力。测量这些测试中使用的竹子的抗压和抗拉强度。2预计这项研究将产生各种更广泛的影响。首先，竹子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，提供短期边坡稳定关键控制，或补救，边坡故障。虽然这项研究可以应用于低技术含量的西方建筑条件，但其主要应用在这一点上，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重要组成部分。第二，可持续性必须是工程发展的一个基本概念;这项研究将有助于了解竹子使用量增加的潜力，以及增加工程中的运动，以重新评估建筑材料的选择。第三，研究团队中将包括一名本科生研究员，这是一项在学生从本科过渡到研究生学习中发现的非常宝贵的技术。第四，有希望的成果可以通过三种传统途径传播：作为工程学杂志上的技术说明;作为在适当会议上提出的论文，例如关于环境可持续性的论文;以及作为在全国年度工程师无国界会议上的发言。第五，这项研究有可能付诸实践：如果结果支持其可行性，则有机会通过马里兰州大学的无国界工程师项目在实地测试该技术。
