摘要
在工程实践基础上,对邯郸东部地基处理方法的设计,施工工艺、质量控制及施工效果进行了分析和比较,在经济技术分析和环保分析基础上,确定了本区地基处理方案的选择原则。提出了当设计地基承载力特征值大于或等于200kPa时,应采用CFG桩法进行地基处理;当设计地基承载力特征值小于200kPa时,东区应采用水泥土搅拌桩(干法)复合地基,西区应采用夯实水泥土桩法复合地基或水泥土搅拌桩(湿法)复合地基,北区和南区应采用水泥土搅拌桩复合地基。
Based on engineering practice, analyzed and compared eastern Handan area foundation processing design, construction technology, quality control and construction effectiveness, with a view to econo-technological and environmental protection analyses, determined foundation processing scheme selection principle in the area. Indicated that designed bearing capacity of foundation eigenvalue is greater than or equal to 200kPa, CFG pile should be used; while less than 200kPa, CDM pile （dry-process） should be used in eastern subarea, tamped cement-soil pile composite foundation or CDM pile （wet-process） in western subarea, while CDM pile composite foundation in northern and southern subareas.
