摘要:
对照江苏省水工建筑地基液化处理现有技术，优化宿迁市黄河故道整治建筑物工程液化地基处理方案，提出对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，并将挡水建筑物的公路桥、工作桥与闸墩采用嵌固的支撑方式，增加整体刚度处理方案。通过陈圩闸、蔡支闸实施效果分析，结果表明：优化方案更适合黄河故道整治建筑物工程现场实际情况，能满足建筑物地基抗震防液化要求，为类似水工建筑物液化地基处理提供借鉴。
Abstract:
According to the existing technology of liquefaction treatment of hydraulic building foundation in Jiangsu Province, optimize the liquefaction foundation treatment plan of the he Yellow River old riverway renovation project in Suqian City, and propose to use cement mixing piles to enclose the liquefied soil layer under the building foundation with an anti-seepage wall, and the building cement mixing piles are applied under the foundation and within a certain range outside the outline to reinforce the soil, and the road bridge, working bridge and gate pier of the water retaining structure are supported by embedding to increase the overall stiffness. Through the analysis of the implementation effect of Chenwei Gate and Caizhi Gate, the results show that the optimized scheme is more suitable for the actual situation of the site of the Yellow River old riverway regulation building project, meet the requirements of measures for earthquake resistance and liquefaction prevention of building foundations, and provide reference for the liquefaction foundation treatment of similar hydraulic structures.
