In situ stress is an important fundamental design and construction parameter in tunnel engineering as the external load of tunnels, especially in case of deep tunnels in which potential geological hazards caused by high in situ stress can be often observed. This paper describes the integration of the acquisition technique and analysis method of tunnel in situ stress measurement via hydraulic fracturing into the infrastructure smart service system (iS3) platform.
