Case Study of the Landslide Disaster Based on the Entropy Function Theory of the Dissipative Structure

Based on the entropy function theory of the dissipative structure, and combined with the characteristics of the landslide disaster of soil-rock mass, the concepts of entropy of landslide, negative entropy of landslide and general entropy of landslide are put forward; the evolving mechanism and conditions of instability of the dissipative structure of landslide disaster system are analyzed, and the corresponding control measures of reducing the entropy-increase and increasing the negative entropy are brought forward; the quantitative calculation method and calculation step of general entropy of landslide system of soil-rock mass are initially discussed; in addition, by combining the engineering practical example in Xiamen of landslide disaster and its prevention and cure, the general entropy of system during and after the landslide are calculated respectively; according to the change of the general entropy of the landslide soil-rock mass system, the feasibility and rationality of the governance measures of landslide are verified.
