Displacement control in irregular deep excavation adjacent to tunnel groups in structural soil: A case study of MJS cement-soil composite piles and grouting rectification

Abstracts: With the gradual development of urban construction, more high-rise buildings with deep foundations are been constructed near tunnel groups. Analyzing how tunnels and surrounding strata respond to diverse construction strategies and challenging conditions during the excavation is crucial. This examination is instrumental in safeguarding infrastructure and minimizing construction expense. This paper explores the deformation response of structures and ground caused by irregular deep foundation pits that are excavated in structural strata adjacent to a tunnel groups (
