At the end of this paper , some testing schemes are designed delicately and researched carefully . there are some parameters including the number of the mode , splitteing ratio , loss and gain needed to be tested . at the same time , any possible problems are anticipated and the follow settlements are also given . by all those researchs above , the paper drow some valuable conclusions eventually 在本論文的最后部分著重對(duì)分路器器件相關(guān)參數(shù)的測(cè)試方案進(jìn)行了設(shè)計(jì)與研究,需要測(cè)試的參數(shù)包括輸出模斑的模式,分束比,損耗和增益;同時(shí),預(yù)測(cè)了可能出現(xiàn)的問(wèn)題,及解決途徑。最后對(duì)前面的分析和研究進(jìn)行了歸納,得出了有價(jià)值的結(jié)論。
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(rèn)識(shí)如下: ( 1 )確定必要的強(qiáng)夯施工參數(shù); ( 2 )對(duì)既有砂性土又有粘性土地基的最佳夯擊次數(shù)的確定方法進(jìn)行了探討; ( 3 )對(duì)試驗(yàn)前各試驗(yàn)小區(qū)的強(qiáng)夯試驗(yàn)方案進(jìn)行了評(píng)價(jià),并提出了優(yōu)化建議; ( 4 )強(qiáng)夯墊層材料的級(jí)配對(duì)夯擊能的消耗有很大影響,級(jí)配好的墊層對(duì)夯擊能的傳遞比級(jí)配差的墊層效果好; ( 5 )強(qiáng)夯地基的變形效應(yīng)主要是指夯后地基不但沉降變形會(huì)大幅度降低,而且剩余沉降變形會(huì)緩慢地發(fā)生; ( 6 )在比較各試驗(yàn)小區(qū)的變形穩(wěn)定性后,按照優(yōu)化后的試驗(yàn)方案進(jìn)行強(qiáng)夯處理,則浦東機(jī)場(chǎng)場(chǎng)道工程地基的變形穩(wěn)定性能滿足設(shè)計(jì)要求,但須在處理時(shí)施加強(qiáng)夯墊層。
