Abstract

Abstract:

To deal with the cracking damage caused by foundation deformation in masonry buildings of the high loess slopes in Kashgar, Xinjiang, the phase change behavior and evolution of order parameter in the loading of buildings are studied by comparing the entropy of the equilibrium phase transformation system to the cooperative system. Order parameter is represented by the angle between vector sums of the crack projected onto the coordinate system. The results show that evolution of the crack in masonry structure is closely related to the free energy of the building. Study on the variation of free energy in the process of building damage and its related factors can help understand the evolution of building damage, and provide a theoretical basis for preventing damage due to foundation
deformation for high loess slopes in Kashgar.

Key words: defect, deformation of foundation, synergetic evolution, high loess slope
