摘要/Abstract

摘要： 某新建城区拟修建于大面积填土上，针对该新建城区的复杂工程地质条件，对天然地基、复合地基等地基基础方案的经济、技术、工期等综合分析和比较，最终采用CFG桩复合地基方案对该区独立基础和条形基础进行计算并设计布桩。CFG桩复合地基是CFG桩、桩间土、碎石垫层联合构成的复合地基，其桩身质量好，承载力可达350 kPa以上。当最大柱荷载小于或等于4 000 kN或土层中有强透水砂卵石层时，均宜采用独立柱基下CFG桩复合地基。

关键词: 填土, 复合地基, CFG桩

Abstract: A new city zone will be built on a large area of backfill, and according to the complex engineering geology conditions, the CFG pile composite foundation scheme was finally selected. The isolated foundation and strip foundation were calculated and piles were designed after comprehensive analysis and comparison on economy, technique and construction period of various approaches like natural foundation and compound foundation etc. The CFG pile composite foundation is a kind of composite foundation that consists of CFG pile, soil among the piles and broken stone underlay. The CFG pile body is of good quality, short construction period, fast construction speed and big bearing capacity which can be more than 350 kPa. The CFG pile composite foundation should be adopted,if the maximum load of a pile is not more than 4 000 kN or there is a sand and gravel bed which is of high hydraulic permeability in the soil stratum.

Key words: backfill, composite foundation, CFG pile
