摘   要 ：为解决多含水体系地下水分布不均，在施工过程中因水位下降引发的临近灌注桩沉降和支护稳定性问题，利用劲性水泥土搅拌连续墙 ( Soil Mixing Wall ,  SMW 工法）结合高压注浆防渗施工、排桩支护技术，配合降水 、锚杆 、内支撑技术，来确保基坑施工的整体安全与稳定，完成多含水层体系下基坑支护施工技术研究。结果表示：SWM 工法中利用方形桩与圆形桩均能满足支护稳定性方面的要求 ，两者桩身直径为 0. 6 m 时能够满足支护稳定性方面的要求，可对此类施工工作提供具体参考价值。

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
