摘要

Natural feature of soils is considered during calculation of horizontal geopressure.K₀ parameter gained from the high-pressure creep equipment is used to calculate horizontal stress of shaft lining with nearly 700 m buried soils in the Juye coal mine, Shandong Province. Analyses prove that there exists a vertical additional stress due to dehydration of aquifer during shaft construction in a thick regolith area.
