DETECTED RESULTS ANALYSIS OF THE MULTIPLE COMPOUND GROUND OF SOFT FOUNDATION OF HIGH-STORIED BUILDING

The paper demonstrates that multiple compound can use different pole materials, different construction methods and make full use of bearing capacity of ground soil in order to eliminate ground liquefaction as well as meet requirements of bearing capacity of ground. Through cost of comparing, prove that multiple compound is a handling method of ground which whose construction method is easy, cost is comparatively economical and deserves being spread. The technology of composite foundation using CFG stake is adopted in improving the bearing strength for soft subsoil. And in this paper,the principle of multiple compound, the characteristics of CFG stake&two ash pile reinforcing soft subsoil and practice data are analyzed. According to the inspection of the engineering effect, the disposition method of composite foundation using CFG stake&two ash pile can achieve the design requirements.This method is economic in cutting down the engineering cost and has better economic and society benefit.
