dimensionless thickness-
( 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。In chapter three, the momentum integral equations and their solutions of two - phase fluids in boundary layer are given and the no - disturbance solutions on the surface of vane are required. leading into the disturbance factor of no - dimension and thickness coefficient ks in boundary layer, the numerical method of finite approximation is used to calculate the boundary layer
