In this paper we combining connecting tunnel project of Subway Line 4 at Xidan-lingjing bystreet in Beijing. To aim at the difficulties of building large-span connecting tunnels in the fine sand layer, through roads and underground pipelines, construction nearby buildings and other project difficulties. Using theoretical analysis, numerical simulation, field tests and other research methods to comprehensive and systemic research the stratum deformation mechanism and process control techniques of shallow excavation method, and a series of results were obtained. Firstly, use the stochastic media theory to analyze the stratum deformation mechanism, concretely analyze the analytic equation of surface horizontal displacement and deformation which were caused by the excavation of single-hole and double-hole tunnel, and further discussion on ground settlement, vertical deformation, surface horizontal displacement and horizontal deformation. Analyzing the main influence factors of surface displacement, and combined with practical work to proof the theory which was applied to shallow buried single-hole tunnel in fine sand layer was scientific.

The key of maintaining the tunnel stability lies on how to deal with the advance core soil ahead of working face, which is obtained on basis of analysis on the problems in high speed railway tunnels with big crosssections in soft surrounding rock or soil. Fullface prereinforcing method by fiberglass bolts can enhance the equivalent rigidity of the advance core soil and control the deformation of the advance core soil, so that arch effect can play its role naturally and assure the excavation safety.
