深基坑开挖支护必须做到可靠安全，饱和粉质土的抗剪强度离散性大导致基坑支护开挖过程中，土体稳定性差，可能造成对基坑整体稳定性的不良影响，甚至造成安全事故。因此本文重点从基坑支护的角度讨论如何提高基坑在饱和粉质黏土开挖过程中基坑自身的稳定性，重点讨论了基坑支护的施工工艺和设计选材。

Pit support must be safe and reliable in the exc-avation of deep foundation , the large discreteness of shear str-ength of saturated silty soil led to in the process of foundation pit excavation poor soil stability, which could have a negative impact on the overal stability of foundation pit, and even cau-se accidents. Therefore, this paper mainly, from the perspective of foundation pit excavation,discusses on how to improve the stability of saturated silty clay in the process of the excavation of foundation pit itself, focusing on the design process and material of construction of foundation pit support.
