Construction Technology of Deep Foundation Excavation Support and Dewatering in Saturated Soft Loess Stratum
Based on the deep foundation excavation project of a hospital reconstruction project in Xi'an,the problems encountered in the design and construction of the foundation excavation support in the saturated soft loess area are analyzed and summarized,and the corresponding treatment measures are put forward.The design countermeasures to be taken in the design and construction process of foundation excavation depth adjustment are introduced,and the principle of giving priority to the use of secant pile waterproof curtain with larger stiffness is proposed.Meanwhile,the importance of"layered excavation,layered support and strict prohibition of over-excavation"is emphasized.
