Abstract:
The stress of high fill culverts in trapezoidal valley terrain is relatively complex, and it is quite different from that of buried culvert and trench buried culvert. In order to explore the mechanical characteristics of high fill box culverts under trapezoidal valley terrain in mountainous areas, centrifugal model tests were conducted to study the impact of different valley width to span ratios B/D and valley slope α on soil pressure around box culverts. The results show that the valley width and slope of the trapezoidal valley terrain have varying degrees of influence on the stress of the high fill box culvert structure, and the influence degree is the greatest when valley slope is in the range of 30°-60 ° and the valley width to span ratio B/D<3. The vertical soil pressure at the top of the culvert, the horizontal soil pressure at the side of the culvert, and the reaction force at the bottom of the culvert are all positively correlated with the width of the valley and negatively correlated with the slope of the valley under the terrain of the valley. When the width to span ratio B/D of the valley is less than 3, the vertical soil pressure concentration coefficient Ks at the culvert top is less than 1. When the valley slope α>30 °, the vertical soil pressure at the top of the culvert begins to transform from stress concentration to pressure diffusion. It is recommended to retain the original trapezoidal valley terrain while ensuring the stability of the slope when designing high fill box culverts. Areas with a width to span ratio B/D<3 and a larger slope of the valley can be selected to cross to ensure the load reduction effect of the terrain on the box culvert.
