水泥土搅拌桩技术在温家桥西闸地基处理中的应用

Application of Cement-Soil Mixing Pile Technology in Foundation Treatment of West Sluice in Wen Jiaqiao

摘要:

针对济南市商河县土马河温家桥西闸闸址存在土层可液化、地基承载力不足及渗流问题,研究采用水泥土搅拌桩复合技术处理工程地基,通过地质勘察、参数优化、稳定性计算及工艺控制,结果显示:闸基承载力从80~120 kPa提升至145 kPa以上,液化指数降至2以下,渗流坡降从1.13降至0.32。对比传统方案,该技术能够节省25%造价,缩短30%工期,并结合黄河故道刁口河工程分析了该技术的推广价值,为黄河冲积平原水闸地基处理提供参考。

Abstract:

The site of west sluice in Wen Jiaqiao on the Tuma River in Shanghe County, Jinan Municipality is faced with liquefiable soil layers, insufficient foundation bearing capacity and seepage issue. This study adopts composite cement-soil mixing pile technology for foundation treatment. Through geological exploration, parameter optimization, stability calculation and construction process control, the results show that the bearing capacity of the sluice foundation rises from 80~120 kPa to over 145 kPa, the liquefaction index drops below 2, and the seepage gradient decreases from 1.13 to 0.32. Compared with conventional schemes, this technology cuts construction cost by 25% and shortens construction period by 30%, and analyzes the popularization value of this technology against the engineering of Diaokou River (the original Yellow River channel). providing technical references for foundation treatment of sluices in the alluvial plain of the Yellow River.
