摘　　要：陕西延长中煤靖边能源综合利用启动项目化工装置场地地层主要由第四纪上覆风积细砂及冲积粉细砂组成。针对地基特点,在场地平整后采用振冲砂桩和碎石桩处理地基,该方法经济简便高效,提高了地基承载力,达到了装置单元设计承载力要求。The stratum where chemical engineering installations are erected for Shanxi Yanchang China Coal Jingbian Energy Sources General Utilization project is mainly composed of Quaternary aeolian find sand and alluvial powder fine sand. With consideration of the foundation conditions, vibroflotation sand piles and gravel piles are used to treat the foundation after the project site is leveled. This method is economic, convenient and effective, and it could obviously improve the bearing capacity of foundation and successfully satisfy the design hearing capacity of installation unit.
