| Abstract: | The functions of geosysthetics in consolidating soft subgrade are described.The basic principles and application of geosysthetics in consolidating soft subgrade are discussed in detail.Furthermore,the conception of coefficient of geotextile-soil is introduced to reflect the performance of geosysthetics.On the basis of analyzing the basic principle and the calculation method of the consolidation,a comprehensive comparison has been made between the reinforced subgrade and the non-reinforced subgrade.And the differences between the operating limit state of geosysthetics and the failure limit state of geosysthetics in consolidating soft subgrade are analyszed.The most reasonable design is given after comparing the proportion of performance to the cost of geosysthetics.Finally,the validity and superiority of geosysthetics in consolidating soft soil subgrade as well as the important functions of geosysthetics in geotechnology are demonstrated. |
