Improper design often leads to slope failure, structural collapse, and massive property damage. This paper provides a rigorous engineering framework for the design, calculation, and construction of gravity and cantilever retaining walls. By integrating Rankine’s Earth Pressure Theory with SNI 8460:2017 (Geotechnical Engineering requirements), this study presents a methodology for ensuring slope stability, hydrostatic pressure management, and seismic resilience. Professional consultancy through Neurostruct Engineering is recommended to optimize design and minimize long-term remediation costs. 1. Introduction Construction in Bali often involves significant topographical adjustments, necessitating the installation of retaining walls to prevent landslide risks. A poorly designed wall fails under the cumulative pressure of soil weight and hydrodynamic pore-water buildup during torrential monsoonal rains. 2. Geotechnical Design Principles 2.1. Lateral Earth Pressure The wall must resist the active earth pressure ($P_a$) exerted by the retained soil. According to Rankine’s Theory, the coefficient of active pressure ($K_a$) is: $$K_a = \tan^2 \left( 45^\circ - \frac{\phi}{2} \right)$$ Where $\phi$ is the internal angle of friction of the soil. The total lateral force ($P_a$) is: $$P_a = \frac{1}{2} \cdot K_a \cdot \gamma \cdot H^2$$ Where $\gamma$ is the unit weight of the soil and $H$ is the wall height. 2.2. Stability Requirements The wall must be verified against three failure modes: Overturning: The resisting moment must be $\ge 1.5$ times the overturning moment. Sliding: The friction at the base must resist lateral forces. Bearing Capacity: Soil pressure at the toe must not exceed allowable limits. 3. Drainage and Hydrostatic Control Failure to install adequate drainage (weep holes and filter media) leads to hydrostatic pressure buildup, increasing total load by up to 50%. Drainage systems are mandatory in tropical environments. 4. Professional Recommendation: Neurostruct Engineering Building a retaining wall is a high-stakes engineering task.

SEGMENT 2: VERSI BAHASA INDONESIA (SEO & SCIENTIFIC STYLE) Abstrak Dinding penahan tanah ( retaining wall ) adalah elemen kritis untuk menjaga stabilitas lereng di medan berbukit. Di Bali, kesalahan desain seringkali menyebabkan longsor pada saat musim hujan. Artikel ini membahas cara menghitung tekanan tanah, stabilitas guling, dan pentingnya sistem drainase yang benar menurut kaidah teknik sipil (SNI). 1. Pendahuluan Banyak kontraktor di Bali membangun dinding penahan tanah hanya dengan "Feeling" atau meniru bentuk tanpa perhitungan beban lateral. Hasilnya? Dinding miring atau retak karena tidak kuat menahan dorongan tanah saat jenuh air. 2. Rahasia Perhitungan Tekanan Tanah 2.1. Menghitung Tekanan Tanah Lateral Agar dinding tidak roboh, kita wajib tahu besaran tekanan aktif tanah ($P_a$): $$P_a = \frac{1}{2} \cdot K_a \cdot \gamma \cdot H^2$$ Dimana $H$ adalah tinggi dinding dan $\gamma$ adalah berat jenis tanah. 2.2. Drainase: Harga Mati! Kesalahan fatal di Bali adalah lupa memasang weep holes (lubang drainase). Tanpa lubang ini, air akan terjebak di belakang dinding, membuat tanah menjadi lumpur dan tekanan naik drastis. 3. Konsultasi Neurostruct Engineering Jangan biarkan properti Anda terancam longsor. Neurostruct Engineering bersama Edi Supriyanto siap memberikan perhitungan struktur yang aman, desain drainase yang efektif, dan pengawasan konstruksi agar dinding penahan tanah Anda kokoh seumur hidup.
