摘　　要：以宿迁市黄河故道整治工程典型建筑物液化地基处理方案为例,提出对水工建筑物基础下液化土层一定深度采用水泥搅拌桩防渗墙围封、建筑物基础下以及轮廓外一定范围并施打水泥搅拌桩对土体加固增加整体刚度优化方案。实施效果表明,优化方案更适合黄河故道整治工程中小型水工建筑物现场实际情况,满足建筑物地基抗震防液化要求。Taking the typical building liquefaction foundation treatment plan of the Yellow River old road remediation project in Suqian city as an example,The optimization plan is proposed to use cement mixing piles to seal the liquefied soil layer at a certain depth under the foundation of hydraulic buildings,and cement mixing piles are applied to a certain range under the foundation of the building and outside the contour to strengthen the soil and increase the overall stiffness.The implementation effect shows that the optimization plan is more suitable for the actual situation of small and medium-sized hydraulic buildings in the Yellow River old road remediation project,and meets the requirements of seismic and anti-liquefaction of building foundations.
