Longitudinal cracks of concrete caused by frost heaving of grouting slurry and free water in ducts is a special damage of post-tensioned PC girders in alpine regions, which affects the safety, serviceability, and durability of the structures significantly. In order to study damage characteristics, borehole and anatomical detections were conducted on damaged girders. The finite element software ABAQUS was used to establish the nonlinear models of frost heaving. Frost heave analysis of grouting slurry and parametric analysis of free water were carried out to study frost heave effects quantitatively. Control indexes of the frost heave ratio of grouting slurry and the volume of free water were obtained. The results show that the frost heaving of grouting slurry and free water occurs successively after grouting the ducts of the post-tensioned PC structures in alpine region, causing concrete to be tensioned repeatedly and cracked along the longitudinal direction. The volume expansion ratio of grouting slurry needs to be controlled within 0.80%, and the maximum should not exceed 1.73%. The volume ratio of bleeding water should be controlled within 0.04%, and the maximum should not exceed 0.52%. Thus, the frost heaving risk of grouting slurry and free water in ducts can be reduced effectively.
