英文
badly graded sand-
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
論文的主要工作和研究認識如下： （ 1 ）確定必要的強夯施工參數； （ 2 ）對既有砂性土又有粘性土地基的最佳夯擊次數的確定方法進行了探討； （ 3 ）對試驗前各試驗小區的強夯試驗方案進行了評價，並提出了優化建議； （ 4 ）強夯墊層材料的級配對夯擊能的消耗有很大影響，級配好的墊層對夯擊能的傳遞比級配差的墊層效果好； （ 5 ）強夯地基的變形效應主要是指夯后地基不但沉降變形會大幅度降低，而且剩餘沉降變形會緩慢地發生； （ 6 ）在比較各試驗小區的變形穩定性后，按照優化后的試驗方案進行強夯處理，則浦東機場場道工程地基的變形穩定性能滿足設計要求，但須在處理時施加強夯墊層。
