无泥型软弱层带变形参数取值研究

Study on evaluation of deformation modulus of no clay weak interbed

分析表明,控制无泥型软弱层带变形模量的主要因素是其粒度成分和所赋存的地质环境条件。通过现场17组变形试验结果,建立了变形模量与各主控因素之间的关系式,并最终以控制因素的变化去揭示不同类型软弱层带变形模量的变化规律,为对不同地段。

Through analysis,it is known that main factors to control deformation modulus of no clay weak interbed are its material composition and geological environment (geostress).Based on a lot of test results,we have established the correlations between deformation modulus and different controlling factors,and revealed the variation rule of deformation parameter.We finally obtain the method to evaluate deformation modulus of no clay weak interbeds of different types in different regions.
