国内高速公路目前处于起步阶段,缺乏实际经验,在学习国外有关软土地基处理经验的基础上,结合工程的特点和具体条件,制定了沪嘉和莘松高速公路的软基处理方案,并分别进行软基处理方面的试验研究。其中包括软土地基处理工艺、测试仪器、材料设备、沉降预估等关键技术的研究,期望从这两条高速公路的实施和工程总结中,合理提出上海地区修建高速公路容许工后剩余沉降量和沉降预估方法,掌握几种软土地基处理技术。这两条高速公路分别由上海市城市建设设计院和上海市政工程设计院设计。
Domestic expressways are in their initial stage at present, lacking of practical experience. On the basis of learning the experience of foreign countries in dealing with soft soil foundation and combining with the characteristics and specific conditions of the project, the paper has formulated the soft foundation treatment programs for Shanghai-Jiaxing-Xinsong Expressway Experimental Research on Soft Foundation Treatment. It includes the research on the key technologies of soft soil foundation treatment, testing equipment, materials and equipment, settlement prediction and so on. It is expected from the implementation and project summary of these two expressways, it is reasonable to propose the allowable post-construction residual settlement in expressway construction in Shanghai And subsidence prediction methods, grasp several soft soil treatment technology. These two expressways are designed by Shanghai Urban Construction Design Institute and Shanghai Municipal Engineering Design Institute respectively.
