某城市外环路工程按一级公路设计,全长近20km,沿线部分路段为松散的人工填土和淤泥、淤泥质土地基,综合考虑工程进度、工程费用和质量的要求,经过对数种软弱地基处理方案的比较优化分析,结合当地的实际土质条件,决定在K11+321～K11+371段50m长内进行水泥搅拌桩治理软弱地基的现场试验。试验结果能满足设计要求,为全面治理道路软弱地基提供参考。
The design of a city’s outer ring road is designed according to the Grade I highway with a total length of nearly 20km. Some sections along the route are loose artificial fillings and silt and silt soil foundation. Considering the project progress, project cost and quality requirements, Based on the comparison and optimization analysis of the soft foundation treatment scheme and the local actual soil conditions, it is decided to carry out the field test of cement mixing piles to treat weak foundation within 50m length of K11 + 321 ~ K11 + 371. The test results can meet the design requirements and provide a reference for the comprehensive control of the weak ground of the road.
