The Experimental Study On The Performance Of New Geotextile Materials And Engineering Application

The Binhai New Area of natural ground water depth is shallow, subgrade offen inwet or moist state, this problem affect the life of pavement structure seriously, to solvethis problem, the paper proposes the use of complex3D drainage geotechnical net. Thisnew geosynthetics exclude groundwater ideas, and proves its feasibility throughexperiments and engineering practice.The paper first introduces the structure and physical characteristics of complex3Ddrainage geotechnical net. Through the experiment on its rate test, compressivestrength, tensile strength, the paper studied and compared it with conventional drainagematerials (general drainage network, crushed stone permeable layer) were compared withtest data, showing the superiority of its material properties the.The paper take the Admiralty Street Town area road and Hangu link roadreconstruction project as examp, analyzed the influence of underground water on theservice life of engineering investment and road. Taking the practical engineering as theexample, compared the drainage time that setting3D drainage geotechnical net and notsetting it. The influence of the road of life and the water discharge time are comparedthrough calculation. Through the completion of the project of pavement deflection value,pavement structure change in the degree of compaction of unconfined compressivestrength by the road test results, reach that conclusion that the application of3D drainagegeotechnical net is valuable in solving problems of road underground water level.
