To carry out foundation pit support,it is necessary to not only consider supporting the rock and soil,but also form an effective water stop curtain.The local basement foundation pit support project adopts a support system consisting of drilled cast-in-place row piles+two layers of reinforced concrete internal support.A three-axis cement mixing pile is used in the passive area to reinforce the soil.The study analyzes the calculation parameters and construction points of the foundation pit,so as to provide reference for similar foundation pit projects,and further improve the development of foundation pit levels in relevant regions.
