Abstract：
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 bearing capacity of installation unit.
