In order to study the influence of geometric alignment of highway circular curve section on water thickness distribution of road area, the standard orthogonal test was established with the leading research variables of the transverse slope, longitudinal slope, road width, and circular curve radius. The water distribution of the road's surface was simulated based on computational fluid dynamics. The influence of transverse slope, longitudinal slope, road width, and circular curve radius on water thickness was compared by numerical analysis. The results show that the larger the number of lanes, the larger the peak value of accumulated water thickness. Under the rainfall intensity of 3.5mm/min, the maximum water thickness of a four-lane circular curve road is 11 mm, six-lane is 16mm, eight-lane is 22mm. The water thickness on the surface of the circular curve road is positively correlated with the height and width and negatively correlated with the longitudinal slope. There is no apparent linear relationship between the radius of the circular curve and the thickness of the water. The influence degree of the water thickness on the surface of the circular curve road is road width > transverse slope > longitudinal slope > circular curve radius.
