Test on Effectiveness of Filled up Ground Treatment with Deep Mixing Pile in Power Plant

the cooling tower and chimney structures of an electric power plant of Wuhan region locate filled up ground,the project is short of time,and the structures are higher strict with bearing capacity.Considering the engi- neering properties of filled up ground underlying it,deep mixing method is adopted to improving filled up ground. On the base of results of field tests,large-area deep mixing construction parameters are determined,and the static cone penetration test(CPT),low strain test,standard penetration test(SPT),plant loading test(PLT)and rod sounding methods are used to inspecting the soil cement uniformity,pile integrality,and bearing capacity of single pile and composite foundation.In the end,some useful conclusions are obtained.
