| The foundatims of the Runway Engineering of Pu-dong International Airport that had been finished and used are applied as background of this dissertation .The examing results of the tests of single-point pounding,the change of the character of foundation soil after pounding and the observation results of settlement of simulation test to runway surface are deeply analyzed.Meanwhile,the monitor informations of deformation and settlement of foundation soil after pounding are analyzed .Based on the research results as above,the deformation effect of dynamic consolidation foundation and dynamic consolidation tests are studied deeply and some valuable conclusion are obtained .The main work and research results of this dissertation are as foulows:1. Confirm neccessary parameters of construction;2. Discuss the method of confirming the best times of pounding for the foundation with both sand soil and clay;3. Appraise the test scheme of dynamic consolidation of each test district before test and make optimization suggestions;4. The grain-size distrilidation of the underlayer of dynamic consolidation has great on consumption of the energy I ,the better the dynamic consolidation effect is;5. The deformation effect of dynamic consolidation foundation is that not only the settlement deformation of foundation will decrease greatly after pounding ,but residual settlement deformation in each test district are compared ,it can be concluded that the deformation stability of foundation of the runway engineering of Pu-dong airport can satisfy the design requirment through dynamic consolidation according to optimized test scheme.But the underlayer of dynamic consolidation should be made when pounding .
