Henry Phạm Đức · Portfolio & Knowledge Systems
Earth, Motion & Science,
engineered side by side.
A curated network of engineering repositories and movement science vaults — from geotechnical instrumentation and automated dam safety monitoring to athletic biomechanics, the kinetic chain, and internal martial mechanics.
Mạng lưới cơ sở tri thức chuyên sâu — từ quan trắc địa kỹ thuật và hệ thống cảnh báo sớm an toàn công trình, đến cơ sinh học thể thao, chuỗi động học và khoa học chuyển động truyền thống.
About & Overview
I am Henry Pham Duc — an engineer and researcher based in Surrey, British Columbia, Canada. My work bridges industrial geotechnical monitoring systems with athletic biomechanics and human movement efficiency.
Tôi là Phạm Đức Hải — kỹ sư và nhà nghiên cứu tại Surrey, British Columbia, Canada. Nghiên cứu của tôi kết nối các hệ thống quan trắc địa kỹ thuật hiện trường với cơ sinh học thể thao và nguyên lý tối ưu hóa lực trong chuyển động con người.
This portal organizes my published technical systems into three primary pillars: Geotechnical Field Instrumentation (16 standard reference manuals, 20 application domains, ADAQS IIoT architecture, and AI diagnostics), Modern Tennis Biomechanics (AI video analysis, 62 mathematical movement formulas, and an 800+ article wiki), and Tai Chi Movement Mechanics (fascial continuity, kinetic grounding, and bilingual encyclopedias).
⚡ Geotechnical Engineering & Field Monitoring
Subsurface Instrumentation & Safety Telemetry
A comprehensive production-grade knowledge base integrating 16 standard field reference manuals, 20 critical engineering application domains, automated ADAQS telemetry, and AI-driven geotechnical diagnostics.
16 Standard Field Reference Manuals
Curated, searchable technical synthesis of the essential manuals engineers rely on daily: John Dunnicliff's benchmark guide, FHWA NHI manuals, USACE Engineering Manuals, Canadian Foundation Engineering Manual (CFEM 2022), Dr. Evert Hoek's Practical Rock Engineering, Burt Look's Investigation Tables, SME Mining Handbook, and ICOLD Bulletin 194.
20 Project Application Disciplines
Instrument layouts, installation protocols, threshold alert levels, and data interpretation criteria across 20 real-world project domains: embankment & tailings dams (ICOLD/ASDSO), deep foundations, urban deep excavations, MSE retaining walls, tunnels & shafts, slope stability, and in-pit mining dykes.
Sensor Architectures & Telemetry
Complete specifications, wiring schemes, calibration formulas, and IIoT network topologies for modern geotechnical sensors: vibrating wire piezometers, ShapeArray (SAAV) 3D deformation chains, MEMS inclinometers, multi-point extensometers, load cells, and wireless mesh networks (RSTAR Affinity / GroundProbe).
GTI Doctor — Field Diagnostic AI
Domain-specific geotechnical AI assistant trained directly on every page of all 16 reference manuals. Instant zero-drift calculations, installation error troubleshooting, threshold verification against TCVN 9398 and USACE standards, and on-site checklist retrieval.
About the Geotechnical Instrumentation Intranet
Engineered as an intranet-style knowledge base for field technicians, geotechnical consultants, and infrastructure owners. Hosted simultaneously across two live GitHub Pages clusters (geoinst.github.io and rstaffinity.github.io) to guarantee zero-downtime access during on-site field inspections and emergency monitoring procedures.

☯ Tai Chi & Internal Movement Arts
Moving Meditation, Decoded Through Mechanics
Fascial lines, pelvic rooting, kinetic loops, and the dialogue between modern athletic science and traditional moving meditation.
Taichi WIKI (Bilingual)
Complete bilingual encyclopedia covering Yang-style long form, push-hands (Tuishou), martial applications, fascia research, joint preservation, and the neurological benefits of slow movement meditation.
Tai Chi Structured Knowledge Base
A multi-tiered progressive curriculum spanning Foundation, Advanced, and Elite mastery: deep-dives into the 10 Classics essentials, dantian mechanics, whole-body tension modulation, and root force transmission.
Taichi NOW (50+ Body Focus)
Curated resources optimized for longevity, recovery, and joint preservation. Gentle yet potent qigong routines, spine mobilization, and 71 archived essays on practice and mindfulness.
The Convergence: Geotechnics, Tennis & Tai Chi
Geotechnics investigates how structures anchor into the earth and transfer colossal forces through soil and rock. Tennis harnesses the ground reaction force through the kinetic chain to propel a ball at high velocity. Tai Chi trains the body to root into the earth, sink mass, and transmit effortless force through fascial elasticity without localized tension. All three disciplines are fundamentally about how force is grounded, organized, and balanced from the foundation up.
