The invention discloses a cement-soil wall arch structure used for strengthening weak soil in a passive region of a foundation pit. The cement-soil wall arch structure is good in stress performance, strong in anti-skidding ability, high in economic efficiency and quite suitable for strengthening a weak soil layer in the passive region of the foundation pit. The novel cement-soil wall arch structure comprises a skirt wall, arch walls and piers. The skirt wall, the arch walls and the piers are all formed by wet-sprayed stirring piles or dry-sprayed stirring piles which are mutually meshed. According to the working mechanism of the cement-soil wall arch structure, pressure of the soil on an active side of the foundation pit is transmitted to supporting protective piles (continuous walls), the supporting protective piles (the continuous walls) transmit the pressure to the skirt cement-oil wall in the passive region, and the skirt cement-soil wall transmits the pressure to the continuous arch cement-oil walls which are connected together through the piers. The cement-soil wall arch structure can fully achieve the anti-pressure performance and the anti-shearing performance of cement soil, and has the advantages of being good in stress effect and cost saving.
