益沅高等级公路地处洞庭湖冲积平原L,主要为软土地基,地基的稳定性成为工程质量的关键,影响高等级公路的使用寿命。本文介绍无机结合料砂砾基层的特性、作用及在高等级公路软土地基中的设计施工技术。实践证明,软土路基填筑中采用无机结合料地表处治层是经济可行的办法,改造后的路基具有良好的性能。
Yiyang to Yuanjiang high-grade highway lies in alluvial plain of Dongting Lake, and its foundation is mainly soft soil foundation. The foundation stability is key point of projects quality, which can influence service life of the high-grade highway. Authors introduce characteristics, functions, design and construction technologies of inorganic binder gravel base in soft soil foundation of high-grade highway. It is commercial and feasible that inorganic binder gravel base used in soft soil foundation, and the reinforced foundation can service wed.
