To mitigate the impact of foundation pit construction on adjacent existing structures, grouting reinforcement techniques are often employed to enhance deformation strength soil. This study focuses expansion project Dayun Comprehensive Hub in Shenzhen, conducting full-scale numerical simulations excavation deep pits elevated railways and examining effects different schemes. The results indicate that single-row double-row schemes increased bearing capacity piles by 23.7% 31.9%, respectively, significantly enhancing structural performance. After reinforcement, maximum position bridge shifted upward, settlement distribution cap beam became more concentrated, indicating effectively controlled ground piles. Furthermore, compared controlling retaining was effective pile deformation, highlighting its advantages complex environments. Although scheme demonstrated superior technical performance, remains preferred option considering efficiency economic factors.
