Direct linear transformation (DLT) method is extensively applied to Close-range Photogrammetry technology because that it does not need initial approximation of inner and exterior orientation elements. But it is hard to acquire the high accuracy when there are no enough control points or when the accuracy of control points is very low. So advisable assumptions and deductions were proposed based on DLT method, and an optimum nonlinear programming model was built. Beside, the improved algorithm was applied in numerical experiments of tunnel deformation and made good result.

Research and test have proved the closeness between elasticity modulus and integrity index of rock mass. The elasticity modulus can be indirectly inferred from the study of rock mass integrity. The borehole image technology and its analytical approaches are used to get the rock mass integrity index(RMDI), which is deduced to have negative linear correlation with rock mass elasticity modulus when it was kept constant. The conclusion is proved to be right by the on-site trial. Otherwise, it contrasted the correlations of RMDI and rock quality designation to the elasticity modulus of rock mass, the result showed that RMDI and elasticity modulus has higher dependency.

Thin film flows, whether driven by gravity, surface tension, or the relaxation of elastic boundaries, occur in many natural and industrial processes. Applications span problems of oil and gas transport in channels to hydraulic fracture, subsurface propagation of pollutants, storage of supercritical CO2 in porous formations, and flow in elastic Hele–Shaw configurations and their relatives. We review the influence of boundaries on the dynamics of thin film flows, with a focus on gravity currents, including the effects of drainage into the substrate, and the role of the boundaries to confine the flow, force its convergence to a focus, or deform, and thus feedback to alter the flow. In particular, we highlight reduced-order models. In many cases, self-similar solutions can be determined and describe the behaviors in canonical problems at different timescales and length scales, including self-similar solutions of both the first and second kind. Additionally, the time transitions between different solutions are summarized. Where possible, remarks about various applications are provided.
