A Multilayered Retaining Strategy for Enhancing Slope Safety in Low-Infrastructure Mountainous Terrains

This research presents a bold and much-needed engineering solution tailored for the often-ignored realities of rural and infrastructure-deficient mountainous regions where landslides pose a recurring threat to life, livelihood, and local development. Instead of relying on expensive geotechnical interventions such as deep piling, reinforced concrete retaining systems, or sensor-based monitoring, this study introduces a simple yet scientifically sound <b>multilayered retaining wall strategy</b> that is modular, field-adaptable, and economically feasible even for the most remote village environments.The strategy integrates four crucial components—(1) <b>gabion walls</b> for foundational support and drainage, (2) <b>biodegradable geotextile wraps</b> made of jute or coir for shallow soil reinforcement, (3) <b>manual surface drainage channels</b> to prevent water accumulation, and (4) <b>low-cost tilt rods</b> as a passive visual early-warning system. Derived from the synthesis of over 25 globally recognized research papers and technical reports, this framework represents the first unified model that combines these elements in a structured, observationally driven design without the need for heavy machinery or digital instrumentation.To validate feasibility, a hypothetical slope case study was developed based on terrain characteristics typical of Himalayan rural belts, including a 30-degree slope inclination, silty soil composition, and seasonal rainfall intensity between 400–600 mm/month. Through sequential application of the layered system, the estimated Factor of Safety (FOS) improved from an unsafe 0.85 to a stable 1.55, demonstrating the theoretical strength of the proposed design. Visual tables, construction checklists, slope profiles, and monitoring logs further enhance its educational and practical usability.This paper is more than an academic exercise—it is a <b>blueprint for grassroots resilience</b>. It bridges the divide between elite engineering models and under-resourced communities, offering a system that is not only technically valid but also <b>implementable by diploma students, local engineers, panchayats, and NGOs</b>. The framework is especially valuable for polytechnic institutions seeking meaningful field projects, for governments aiming to protect rural infrastructure, and for disaster management bodies exploring cost-efficient, community-inclusive approaches to slope stabilization.By championing affordability, modularity, and hands-on observation, this research proves that <b>civil engineering innovation can thrive without high budgets—only requiring clear vision, layered design thinking, and a commitment to protect those most at risk</b>.本研究针对常被忽视的乡村及基础设施匮乏山区的实际境况，提出了一项大胆且亟需的工程解决方案——滑坡始终对当地生命、生计与地方发展构成持续性威胁。相较于依赖深层打桩、钢筋混凝土挡护系统或基于传感器的监测等昂贵岩土工程措施，本研究引入了一种简洁却科学可靠的**多层挡土墙方案（multilayered retaining wall strategy）**，该方案具备模块化、现场适配性强的特点，即便在最偏远的乡村环境中也具备经济可行性。 该方案整合了四大核心组件：(1) **石笼挡墙（gabion walls）**，用于基础支护与排水；(2) **黄麻或椰壳纤维制成的可降解土工织物包裹层（biodegradable geotextile wraps）**，用于浅层土体加固；(3) **人工地表排水沟（manual surface drainage channels）**，以防止积水；(4) **低成本倾斜杆（low-cost tilt rods）**，作为被动式目视预警系统。 本框架整合了全球25余篇顶尖研究论文与技术报告的成果，是首个将这些元素整合为结构化、基于观测的设计模型，无需重型机械或数字监测设备。 为验证可行性，研究团队基于喜马拉雅乡村地带典型的地形特征构建了一则假设边坡案例：边坡倾角为30度，土壤成分为粉土质，季节性降雨强度介于400–600毫米/月。通过分层系统的依次应用，预估**安全系数（Factor of Safety, FOS）**从不安全的0.85提升至稳定的1.55，证明了所提设计的理论强度。 配套的可视化表格、施工清单、边坡剖面图与监测日志，进一步提升了该方案的教学与实用价值。 本研究绝非仅停留在学术层面——它是一份**基层韧性蓝图（blueprint for grassroots resilience）**。它弥合了高端工程模式与资源匮乏社区之间的鸿沟，提供了一套不仅技术可行，还可由**专科毕业生、本地工程师、乡评议会与非政府组织（NGOs）**落地实施的系统。 该框架尤其适合寻求优质实地项目的职业技术院校，致力于保护乡村基础设施的政府部门，以及探索低成本、社区参与型边坡加固方法的灾害管理机构。 本研究倡导可负担性、模块化与实地观测，证明了**土木工程创新无需高额预算——仅需清晰的愿景、分层的设计思维，以及保护最弱势群体的承诺**。
