摘要
由于软土具有压缩性高、含水量大、强度低和透水性差等特点,在软土地基上修建高速公路时,面临的首要问题是路基的稳定和变形,特别是对路面变形要求非常严格的高速公路工程,控制软土地基的过量沉降变形成为关键性的技术问题。
Due to the characters of soft soil, such as high compressibility, bulky water content, low strength and bad hydraulic permeability, the first problem in constructing expressway on soft soil ground is the stability and deformation. Especially for the expressway which is strictly limited in pavement deformation, the control of excessive settlement of soft soil ground is the key technical problem.
