摘要

    摘要
  • 摘要: 目前土工合成材料加筋技术被广泛应用，但人们对于加筋土中筋材与土间的相互作用的机理的认识还不够深入，因而在设计中总体上趋于保守。结合岩土工程的设计理论，指出土工合成材料在设计方法方面的不合理性；对于加筋挡土墙、加筋土坡、加筋软土地基上的土堤和桩网结构的设计分别进行了讨论；结合一些案例中的实测和预计的筋材应变和应力，进一步指出目前设计的保守性。最后指出，目前基于极限平衡法的设计不尽合理，而通过变形协调的筋土共同作用的研究，采用更能反映其相互作用机理的设计方法是非常必要的。
    Abstract: During the past three decades, geosynthetic reinforcement has been used extensively in geotechnical structures, but the mechanism of interaction between reinforcement and soil is not fully understood, as a result, the conservatireness in the design is found frequently. The conservatireness of design method for geosynthetic-reinforced soil structures is examined. Some discussions on the design of geosynthetic retaining walls, reinforced fill slopes, reinforced embankments over soft soil foundations and reinforced piled embankments are presented. On the basis of the recorded strain and stress in a number of published field case histories, the conservatism of design is further pointed out. It is indicated that the research on the interaction between reinforcement and soil is very important, and that the design method on basis of deformation coordination is necessary.
