Comprehensive constrained inversion makes full use of detailed vertical resolution of well data and horizontal dense sampling, greatly improves resolution of impedance profile greatly.
Four methods of sampling in road and bridge construction are introduced in this paper. They are sampling of known distances, known horizontal angles, known elevations and plane point position.
In Empirical Study, the scope of sampling including the "Chang-zhu-tan District" of horizontal strategic alliance enterprises already established or soon to be established.
