摘   要 ：為解決多含水體系地下水分布不均，在施工過程中因水位下降引發的臨近灌注樁沉降和支護穩定性問題，利用勁性水泥土攪拌連續墻 ( Soil Mixing Wall ,  SMW 工法）結合高壓注漿防滲施工、排樁支護技術，配合降水 、錨桿 、內支撐技術，來確保基坑施工的整體安全與穩定，完成多含水層體系下基坑支護施工技術研究。結果表示：SWM 工法中利用方形樁與圓形樁均能滿足支護穩定性方面的要求 ，兩者樁身直徑為 0. 6 m 時能夠滿足支護穩定性方面的要求，可對此類施工工作提供具體參考價值。

關鍵詞：多含水層體系；錨桿；基坑支護；內支撐施工

Abstract:To solve the problem of uneven distribution of groundwater in multi aquifer systems and the settlement and support stability of adjacent cast-in-place piles caused by water level drop during construction, the Soil Mixing Wall (SMW) construction method combined with high-pressure grouting anti-seepage construction and pile support technology, combined with precipitation, anchor rods, and internal support technology, is used to ensure the overall safety and stability of foundation pit construction in multi aquifer systems. The research on foundation pit support construction technology in multi aquifer systems is completed. The results indicate that both square and circular piles in SWM construction method can meet the requirements of support stability. When the diameter of the pile body is 0.6m, both can meet the requirements of support stability, which can provide specific reference value for such construction work.

Key words: multi aquifer system; anchor rod; excavation support; internal support construction; SMW construction method pile
