( 1 ) systematic triaxial compression tests are made for the sand reinforced by various national geosynthetics. comprehensive investigations into the interaction characteristics are also made between sand / lime fly ash and various national geosynthetics by direct shear tests and pull out tests, which can help choosing geosynthetic type and understanding the geosynthetic reinforcement mechanism ; ( 2 ) this paper is also firstly systematically presents the results of a comprehensive investigation into the interaction characteristics between lime fly ash and various national geosynthetics ; ( 3 ) by non - linear fem, the influence of the modulus of geosynthetics, the thickness of the soft ground and the width of the foundation on the effectiveness of geosynthetic reinforcement are also studied ; ( 4 ) the main conclusions are as followed : ( geotextiles are likely to be suited for projects allowing high displacement, polyester warp knitting geogrids and oriented geogrids for projects allowing medium displacement, glass fiber geogrids for projects allowing low displacement and geonets for secondary projects. ( the confining effect of fill material to act on different kinds of geosynthetics varies largely, which must be considered
( 1 )本文利用三軸壓縮試驗,比較各種國產土工合成材料對
砂土的加筋效果;利用直剪試驗和拉拔試驗,比較各種國產土工合成材料與
砂土或石灰粉煤灰的界面摩擦特性,深入研究土工合成材料的加筋機理,首次明確提出加筋土工合成材料的選型原則; ( 2 )本文首次系統地研究了石灰粉煤灰與各種國產土工合成材料的界面摩擦特性; ( 3 )本文採用有限元法,系統研究了加筋模量、軟土地基厚度、基礎寬度等因素對土工合成材料加固軟土地基效果的影響; ( 4 )本文主要結論如下: (無紡土工
織物適合用於允許大變形的加筋土工程;滌綸纖維經編土工格柵和塑料拉伸土工格柵適合用於對變形有較嚴格要求的加筋土工程;玻璃纖維經編土工格柵適合用於對變形有嚴格要求的加筋工程;土工網適合用於低等級的加筋土工程。

Although reducer can avoid step sense and oscillation partly, the strap transmission will influence orientation precision ( it is key norm to the small metallographic sample cutting machine ), so plan to use step motor to drive the screw directly, the step motor at low velocity, which is not drived by the subdividing drive system, will have obvious oscillation and noise that would influence the cutting function, the usage life and sample structure
由於步進電機是通過皮帶輪減速來驅動絲杠,進而帶動
砂輪片前進和後退,雖然減速能部分消除步進感和振動,但皮帶傳動會影響定位精度,定位精度對精密切割機十分關鍵的技術指標。採用步進電機直接驅動絲杠,未經細分驅動的步進電機在低速運行時,有明顯的步進感、振動和噪聲,從而對切割的性能、
