Zusammenfassung:The invention relates to the technical field of tunnel portal reinforcement, in particular to a bedding and unsymmetrical pressure soft rock tunnel portal reinforcement structure of an oblique crossing structure and a construction method. The tunnel structure comprises a tunnel body arranged in a bedding slope, a frame beam is arranged on the high-terrain side of the tunnel body, and a pile foundation is arranged on the low-terrain side of the tunnel body; the frame beam is arranged on the surface layer of the bedding slope, and the bedding slope is connected with the frame beam through a pre-stressed anchor cable. The method has the advantages that the pre-stressed anchor cables, the frame beams, the pile foundations, the pile foundation crown beams and the retaining walls are adopted, so that the problem of reinforcement before the unsymmetrical pressure tunnel enters the hole, the problem that the tunnel is located on a bedding side slope and prone to landslide and the problem of semi-open and semi-hidden
