An Analysis of the Impact of the Natural Void Radio of Cohesive Soil on the Calculation of the Backwater Height of the Highway Bridge

Abstract:

We discussed the impact of the natural void radio of cohesive soil on the calculation of the backwater height of the highway bridge. Firstly, we discussed the principle of the calculation of the backwater height and the method to calculate the backwater height of the highway bridge which was used by the design unit. Secondly, we analyzed the impact of natural void radio of cohesive soil by using a true project. We found that the method to calculate the backwater height which was used in the Hydrological Specifications for Survey and Design of Highway Engineering was not perfect. Finally, we should correct the parameter of the mean median grain which was decided by the natural void radio of cohesive soil.
