Experience Summary

Dr. Huang, president and principal of the firm, has strong expertise and extensive research and consulting experience in geotechnical and geological engineering. He holds 14 research publications including four in the world leading research journals. The most recent paper is about poro-elastic theoretical model for hydraulic fracturing in-situ stress measurement. The paper has been collected into the Society for Mining Engineering¡¯s permanent literature. The paper has presented the new model through review of the history of the model development in the field of poro-elasticity and effective stresses. Huang¡¯s model made significant contribution to rock mechanics both in understanding of effective stresses in saturated porous medium and in understanding of the effect of rock anisotropy on pore pressure and effective stresses. He also served as technical paper peer reviewer for International Journal of Rock Mechanics and Geotechnical Testing Journal. He is an Adjunct Faculty Member at Western Washington University and opened “Soil Mechanics” and “Slope Stability” courses. He has extensive consulting experience in the area of Western Washington State and knows glacial geology and soils well. He will conduct and manage all the engineering aspects for Merit’s projects in order to maintain quality control, and provide final review on the projects so as to assure quality that is consistent with the standard of care in the industry.

Key Accomplishments/Projects

Dr. Huang has successfully (1) derived a complete solution of pore pressure in saturated medium and developed a general poro-elasticity model for hydraulic fracturing in-situ stress measurement. Made significant contributions to rock and soil mechanics in understanding effective stresses, anisotropy of pores of rock and soil, and their effects on failure mechanism; (2) made significant findings in the field of mechanics of rock joints under cyclic direct shearing loading through a comprehensive laboratory investigation, designed and manufactured a computer controlled precision direct shear testing machine; (3) implemented and setup a laboratory experimental system for hydraulic fracturing test with initial pore pressure, and (4) initiated idea and implemented laboratory experimental setup to measure the compressibilities rock bulk and rock solid using strain gauged cylindrical rock samples. Dr. Huang has authored more than 100 technical reports related to glacial geology and geotechnical engineering. Some representative projects in construction industry he has completed include: slope stability investigation of Blue Canyon at Lake Whatcom Watershed, geotechnical and hydrogeological investigation on Point Whitehorn, groundwater investigation and contaminant transport dispersion analysis for a wastewater treatment plan in Bellingham, GP and Port of Bellingham¡¯s 200,000 SF warehouse on landfill, Western Washington University (WWU) Haggard Hall/Wilson Library renovation project ($20,000,000 value), WWU Ridgeway Dormitory ($10,000,000 value), and Whatcom Community College Learning Resources and Fine Arts building ($8,000,000 value).
