Discussion on the Settlement Calculation of Subgrade Under High Fill in Airports

Till today,there are no uniform rules and so less literatures on the settlement observation and calculation of deep fill related to airports.Therefore,we've encountered so many problems to be solved in the engineering,such as how to choose the most suitable way to go on the settlemtn observation and calculation,how to differ from various methods about regression analysis and regession curve adopted in the treatment of the actual datas,how to make the requirement of consolidation degree,how to arrange the time for observation,should we consider the affection the airplane's loading does to the settlement,how to ensure the reliability of the conclusion and so on.Through the practice in the engineering,combining with referrence to the conclusion in some other resembled engineering,we achive a lot and get some useful realization.In the paper,we introduce them as sollowing to study together and hope it would do good to the airport construction of our country.
