The dredged sediments with stabilization can to be reused as construction and building materials in civil engineering works.
Therefore, raw sediments should be stabilized before their beneficial use in civil engineering works.
The production rate of FA is higher than the rate of recycling, and the reuse of FA in civil engineering applications such as roads [5] will have significant environmental benefits, reducing air and water pollution [4].
The geotechnical engineering properties obtained from laboratory tests for both dredged sediments are listed in Table 1.

Geotextile has been commonly used in civil and geotechnical engineering applications, and the majority of geotextiles is made of nonwoven fabrics.
Introduction The use of geotextile in civil engineering provides soils with functions of reinforcement, drainage, filtration, separation, and moisture barrier, and on the other hand, it also prolongs the life time of civil engineering, shortens construction time, saves raw materials, decreases the engineering cost, and simplifies maintenance.
Geotextiles used to be made of woven fabrics of synthetic fibers; however, due to the excellent performance and low production cost, nonwoven fabrics have now replaced woven fabrics and have been used in soil, rock, and land surface engineering to be part of artificial structures or systems [1-5].
Therefore, the optimal parameter of needle-punch depth is 0.5 cm, the geotextiles made with such a parameter possess good mechanical properties, and thus are suitable for engineering in soil erosion control, as well as road bases and slope stabilization.

Safety Evaluation of A380 Wake Turbulence Separation Jianguo Kong Department of Air Traffic Management, Civil Aviation Flight University of China, 618307, Guanghan, Sichuan,China kongjianguo2007@126.com Keywords: Wake turbulence separation, Wake turbulence risk, Safety evaluation, Safety target level Abstract: CAAC (Civil Aviation Administration of China) set a standard on A380 wake turbulence separation right after China Southern Airlines brought in Airbus A380 in 2001.This paper considers from the possibility of the latter aircraft wake turbulence influencing the preceding one, which means the wake turbulence risk, makes safety evaluation on the wake turbulence separation standard of the preceding aircraft as A380, and the latter one as heavy type, medium type and light type, based on the safety target level that ICAO (International Civil Aviation Organization) authorized.
Introduction Safety is the life of civil aviation, thus it’s very important to make safety evaluation on all sorts of control separation and wake turbulence separation [1-5].
Before A380 enters, the civil aviation aircraft was divided into three levels based on the maximum take-off weight: heavy type, medium type, light type.
By the calculation of Xu Xiaohao from TianJin civil aviation university that is more reasonable, and the air traffic management rules sets A380 wake turbulence dissipating time is 3 minutes.
