Abstract

Abstract

This paper presents the analysis of the present-day structural activity of the Shenzhen fracture zone in terms of the micro-seismicity, fault displacement monitoring and present-day crustal stress measurements. A numerical simulation of the present-day three-dimensional tectonic stress field was then used to make a quantitative calculation of the present-day activity magnitude range at the intersection between the Shenzhen fault zone and the water diversion tunnel, and the included angle between the axial orientations in different parts of the water diversion tunnel and the maximum horizontal principal compressive stress, and to infer the present-day structural stress state of the deeply-buried sectors of the water diversion tunnel. The research results both in seismic activities and risks and in rock and soil stability can be used by means of fuzzy mathematics to assess the crustal stability of the water diversion tunnel project, providing a basis for the engineering designing and construction.
