摘　　要：支护结构应力能力与深基坑压力之间的平衡关系是确保支护稳定的基础,为此,论文对复杂环境下深基坑降水开挖支护稳定控制技术进行研究。从静止土压力,在降水环境下的主动土压力两个方面对钢板桩支护结构的应力需求进行分析,结合分析结构,设置具体的支护构件以及支护措施。在实际应用过程中,正常情况下深基坑位移变化稳定在2.00 mm以内,表现出了较高的稳定性。The balance relationship between the stress capacity of support structure and the pressure of deep foundation pit is the basis to ensure the stability of support.Therefore,this paper studies the support stability control technology of deep foundation pit precipitation excavation in complex environment.The stress requirements of the steel plate pile supporting structure are analyzed from the static soil pressure and the active soil pressure under the precipitation environment,and combined with the analysis of the structure,the specific supporting components and supporting measures are set.During the practical application process,the displacement change of the deep foundation pit is normally stable to within 2.00 mm,showing a high stability.
