LIFTING AND RECTIFYING DESIGN OF COALMINE TRANSSHIPMENT GALLERY

Based on analyzing the reason of the settlement and slope of transshipment gallery in coalmine, numerical simulation was firstly used in analyzing the damage of the building and comprehensive uplifting underpinned piles under column foundation and intercepting brace columns. With analyzing structural function, rotating axis, the intercepting position of column, loading point layout and the decision of load and displacement value were stated. Numerical simulation method was used to prove it. Expected targets were achieved in post construction and good effect of treating the specific structure was obtained.
