摘　　要：对地基沉降量及沉降差接近规范上限的工程,需根据建筑物地基土质情况选择合适的地基处理方案。文中结合工程实例,对某泵站下的软土地基采用水泥土搅拌桩加固的方案。该方案有效减少了地基沉降对泵站结构安全的影响,加固效果良好,较其他地基处理方式,节省了施工费用。可在同类工程中推广应用。For the project where the settlement amount and settlement difference of foundation are close to the upper limit of the code,appropriate foundation treatment scheme should be selected according to the soil condition of the building foundation.Combining with the engineering example,the scheme of cement-soil mixing pile is adopted to reinforce the pump station on the soft soil foundation.The scheme effectively reduces the impact of foundation settlement on the structural safety of the pumping station,has good reinforcement effect,and saves construction cost compared with other foundation treatment methods.It can be popularized and applied in similar projects.
