摘要
软基处理在公路建设领域是个非常重要的技术问题,处理是否得当直接关系工程质量好坏。狮子洋通道工程软土普遍分布,且沿线控制因素庞杂,导致该项目的软基处理难度非常大。综合考虑路基填土高度、软基路段地层特点(包括覆盖层特性、软土层埋深及厚度、物理力学性质指标)、路基稳定及沉降控制指标、差异沉降、沿线城镇发展制约、绿色低碳要求等因素,在保证质量的前提下,兼顾经济性和新材料、新技术的应用,采取表层固化、排水固结、复合地基及轻质土路基等单一或组合处治方案,并体现绿色公路理念。
Soft foundation treatment is a very important technical problem in the field of highway construction,and the proper treatment is directly related to the quality of the project.The soft soil of the Shiziyang Link Project is widely distributed,and the control factors along the project are complicated,which makes the soft foundation treatment of the project very difficult.The factors such as subgrade fill height,stratum characteristics(including overburden characteristics,soft soil depth and thickness,physical and mechanical property indexes),subgrade stability and settlement control indexes,differential settlement,urban development constraints along the route,and green and low-carbon requirements etc.are taken into account comprehensively,and under the premise of ensuring quality,considering the application of economic and new materials and new technologies,single or combination treatment schemes such as surface solidification,drainage consolidation,composite foundation and light soil subgrade are adopted,and the concept of green highway is reflected.
