1、精品办公文档Thank you,prof.My name is .I m from .I am very pleased to be here to join this forum.The topic of my presentation is properties of rapid construction materials for soil pavement of field airfield.As is shown in the picture,the main parts of my research are about soil pavement.My presentation w

2、ill include these four parts:First,some background information about this research;second,the main work we have done;third,some conclusions we have got and the last:innovation and presentation of our published papers.Why I choose this item?I think it can be illustrated from the following four parts.

3、First,the existing quantity of airfields is still not sufficient and the airfields have many shortcomings especially in war time.Second,the complementary facilities,such as highway runways are far less than airfields,however,have more weakness.Third,a certain amount of field airfield is quite necess

4、ary considering some emergencies such as rescue and disaster relief.Forth,the field airfield can fill the void of airfield and they can be combined to be airfield network.The meaning and aim of this research contains three parts.Fast,convenient and validity,fast means the field airfield must be cons

5、tructed 精品办公文档as fast as possible,convenient means the construction should need the minimum equipment,labor and materials considering the actual construction condition,validity means the constructed airfield is able to support the operation of given aircraft in specifically time.Just like many other

6、 territories,the situation of the research is that the U.S.Army takes advanced line.The U.S.Army declares that they can reach to anywhere on the earth in 96 hours,the most important method for force projection is though aircraft,thus rapid construction of pavement is the key problem for rapid force

7、transportation.The main work we have done can be summarized as four parts,materials choosing,scheme making,mechanical properties research and water-stable properties research.We choose two kinds of soils,which are got from Xian,Shanxi province and Jiuquan,Gansu province separately.The sand from Ba R

8、iver was considerate to investigate the influence of sand to the properties of stabilized soil.The chosen three kinds of powders are cement,lime and new-type stabilizer developed by Changan University.The principles in considering the function of 4 kings of fibers are referring different length,type

9、 and mixing them.文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2F4S2文档编码:CU7K5O9E3D1 HM1K10V6E7Y6 ZT2D2E2

16、e proposed to distinguish the affecting factors in making experiment scheme.They are powder control,fiber control and other factors.Taking powder control for example,the dosage of cement is respectively 6%,8%and 10%when the soil is stabilized only by cement,while the dosage of cement decrease to 3%,

17、5%and 7%when the lime is addicted to stabilized soil.The following two factors are stabilizer and sand.Six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil.The aim of compaction test is to find the maximum dry density a

18、nd optimum moisture content.The aim of compression strength test is to determine the optimum dosage of cement,lime,powder stabilizer and fiber,meanwhile evaluating the performance of stabilized soil.The aim of splitting tension strength test is similar to compression strength test,the left picture i
