Abstract: Weak surrounding rock tunnel construction with shallow burying under unsymmetrical pressure is a common type in engineering construction. This kind of tunnel has poor stability， difficulty in construction technology and high quality requirement. In order to successfully complete the construction task and ensure the construction quality，it is necessary to strictly implement the construction technology. This paper introduced the construction process flow and technical measures of the weak surrounding rock tunnel construction with shallow burying under unsymmetrical pressure， and pointed out the problems required attention in the construction，it can provide inspiration and reference for similar engineering construction.

Key words: shallow burying under unsymmetrical pressure, weak surrounding rock, tunnel construction technology, initial support, lining construction
