【摘要】 以某高速公路软基加固处治工程为依托,采用常规土工试验方法研究了软基加固处治前后软土物理力学性质的变化规律,并采用真空冷冻升华技术与SEM(扫描电镜)以及灰色图像处理三者相结合的方法研究了加固处治前后软土微结构的变化规律。更多还原

【Abstract】 In this paper, based on the soft clay subgrade improvement engineering of certain highway, the authors adopted the conventional civil test methods to study the physical and mechanical properties change of soft clay before and after its improvement. Meanwhile, combined vacuum freezing evaporation technology, SEM as well as gray drawing treatments, microstructural variations of soft clay before and after its improvement was also researched.更多还原
