摘　　要：随着我国对进口石油的增加,需在沿海地区建设大批储罐;许多储罐不得不建在软土地基上,这些软土地基压缩性高、承载力低,不经处理,不能满足储罐对基础承载力及沉降和不均匀沉降的要求。在工程中,为了提高软土地基的承载力、减少沉降和不均匀沉降,工程采取了各种措施,例如砂井预压、碎石桩、水泥土深层搅拌桩、水泥粉煤灰碎石桩及刚性桩等。文章介绍了水泥土深层搅拌桩在储罐项目中软土地基处理的应用。As China＇s oil imports increased,the need to build a large number of tanks in coastal areas;many tanks have built in soft soil,the high compressibility of these soft,low bearing capacity,without treatment,can not meet the foundation bearing capacity and settlement of the tank and the differential settlement requirements.In the project,in order to improve the bearing capacity of soft soil,reducing settlement and differential settlement,has taken various measures such as pre-press Sand,gravel piles,deep soil cement mixing pile,cement,fly ash and gravel pile rigid piles.This paper introduces the deep soil cement mixing pile in soft ground storage tank project in processing applications.
