  2. ( 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

  3. The diagenesis may result in the variations in pore structures of sandstone reservoirs ; the compression and cementation may lead to the decrease in valid primary porosity of sandstones, and the secondary porosity generated by solution may serve as main oil storage spaces

    壓實作用和膠結作用降低了砂巖的原生孔隙度，溶解作用產生的次生孔隙成為主要的汕氣儲集空間。
  4. For the purpose of finishing secondary compression deformation of soft clay early, too large opr was not necessary

    以提早完成基準期次壓縮變形量為目標，過大的超載比是沒必要的。
  5. It was found that longer surcharge preloading duration could make the total magnitude of deformation of soft clay larger, and the more surcharge preloading duration and the larger opr, the less magnitude of secondary compression deformation of soft clay after unloading was, compared with that under permanent pressure loading

    研究表明，超載作用時間過長會使地基的總變形量增加，相對于等載預壓過程，超載的作用時間越長、超載比越大，超載卸除后的次壓縮變形越小。
  6. Based on the new model, the influences caused by soil structure, apparent preconsolidation pressure, the re - compression index, the coefficient of secondary compression, the magnitude of loading, the coefficient of permeability, the rate of loading, the thickness of clay, the self - weight, the layered property etc, in the process consolidation of soil with structure, are analyzed in detail. the difference between the present model and yin & graham model was also given

    基於本文新建模型，分析論述土結構性、表觀前期固結壓力、再壓縮系數、次固結系數、荷載增量大小、滲透系數、加荷速率、固結層厚度、自重應力隨深度變化和土體成層性等對土固結的影響，比較本文模型與yin & graham模型的異同，闡述土結構性和流變性對軟土固結壓縮行為的影響。
  7. However, it is shown that the secondary compression is obviously influenced by load

    大量的試驗表明荷載對次固結有較明顯的影響。
  8. Because the high pore - water ratio, lower strength, high compression all are the characteristics for the soft foundation. therefore, per - loading technique is usually adopted to get rid of most deformation due to primary and secondary consolidation before construction. even so, the foundation settlement after construction will exist for a long period

    軟粘土路基在外荷載作用下，其沉降一般是比較大，通常在建造前一般會進行較長時間的堆載預壓，以消除大部分固結沉降和次固結沉降，盡管如此，路面的工后沉降仍然會在很長時間內繼續存在。
