摘要
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,首要面临的是路基的稳定和变形问题,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将成为公路工程建设的关键技术问题所在。
Due to the character of soft soil, such as high compressibility, bulky water content, low strength and bad hydraulic permeability, the first confronted problem is the stability and deformation of roadbed when expressway is constructed on soft soil ground. Especially for the the expressway strictly limited in pavement deformation, the control of excessive settlement of soft soil ground becomes the key engineering technique problem.
