CMPCC-two-dimensional-surface-wave-based method for detecting quaternary active fracture position along railway

The invention discloses a CMPCC-two-dimensional-surface-wave-based method for detecting quaternary active fracture position along a railway. The method comprises the following steps: S1, carrying outlarge-range remote sensing interpretation, field investigation and groove detection, and obtaining at least one to two active fault exact observation points on a fault within a certain range of a line; S2, on the basis of the S1, carrying out high-precision remote sensing interpretation, combining landform investigation, adjusting possible plane distribution positions of the fault, and determiningremote sensing and landform observation points near the line; and S3, selecting typical remote sensing and landform observation points near the line, and carrying out CMPCC two-dimensional surface wave measurement verification. By means of the method, reliable movable fracture observation points distributed along the railway can be further increased, and investigation design and construction protection are facilitated. Th
