英文摘要	The in-situ stress field is a key factor controlling the successful construction of a large number of underground structures in mountainous areas, and is intensively affected by the mountain-valley topography. The effects of mountain-valley morphology (the width of the mountain top platform, mountain height, slope angle, and width of the valley bottom) on the distribution of the in-situ stress field were analyzed and interpreted using numerical modeling techniques, where the spatial distribution and maximum values of the horizontal and vertical stresses were analyzed. The results showed that there existed a critical value of the topographic influence depth, where the in-situ stress distribution varied significantly as mountain-valley morphology, after which the influence diminishes. Tectonic action has a more remarkable influence on the in-situ stress distribution than gravitational action under the same mountain-valley morphology. Moreover, the relationships between the magnitudes of these stress components and the morphology variables are described using empirical formulas, which can be directly applied to different topographies to rapidly achieve a rational estimation. The findings of this study can be very useful for quickly understanding the in-situ stress distribution and as stress measurement guidelines.
