RockPlane NX
Web-based limit-equilibrium verification of planar rock-slope stability — Hoek-Bray geometry, Mohr-Coulomb and Barton-Bandis criteria, active anchors, passive nails, drape and cable meshes. Opens in any browser — no installs, no hardware keys.
What it does
Sliding and overturning factor of safety — real-time FS on the wedge under static and pseudo-static seismic conditions, with colour coding for safe / marginal / unsafe.
Two failure criteria — classic Mohr-Coulomb plus non-linear Barton-Bandis (JRC, JCS) for rough rock joints at low normal stress, with the full diagnostic panel exposed.
Four water states — ponded water at the toe, uplift on the failure plane, thrust in the tension crack, pervious-slope hydraulic connection — with four configurable pressure distributions.
Pseudo-static seismic action — NTC §3.2 and §7.11.3, configurable horizontal coefficient kh and direction Ω, plus a generic external force for road loads or overlying structures.
Nail, anchor and mesh reinforcement — pre-tensioned anchors (NTC §6.6 with ξ and γRa,t), passive nails (NTC §6.7 SoilNail Variant A with Clouterre 1993 N-V interaction), drape mesh R1 and cable panels R2 with full design-resistance breakdown.
Closed-form auto-design — when FS falls below target, the auto-designer solves for nail rows, positions and spacing in milliseconds; an optional Gemini-powered AI layer comments the design and proposes motivated refinements.
2D section and interactive 3D view — real-time wedge plot with force vectors and dimensions, plus a navigable 3D model of the block, nails, plates and meshes — four presets (iso, front, side, top).
Word report, DXF drawing, Trispace handoff — eight-section DOCX with a 99-test validation annex, AutoCAD-ready DXF R12 with wedge, nails, water levels and dimensions, and one-click handoff to Trispace NX via secure 5-minute token.
NTC 2018, Eurocode 7 and Eurocode 8 — characteristic values plus NTC §6.8 Approach 1 Combination 2, EC7 DA1, DA2 and DA3, with the applied partial factors always visible.
Who it’s for
Geotechnical engineers · Geologists · Slope designers · Mining and quarry engineers · Infrastructure consultants. RockPlane NX is built for those who today verify rock-slope stability with spreadsheets or desktop tools, and want a single web environment that goes from limit-equilibrium check to fully-designed reinforcement with traceable normative output.
Why it’s different
Runs directly in the browser, no installation required.
Covers both Mohr-Coulomb and Barton-Bandis criteria, with the Barton-Bandis diagnostic panel exposed in plain sight.
Reinforcement is not just modelled — it is designed: closed-form sizing plus optional AI review.
Six selectable normative frameworks (characteristic, NTC §6.8 A1-C2, EC7 DA1-C1, DA1-C2, DA2, DA3) with the applied partial factors always visible on screen.
