Under the combined effects of various external factors, such as temperature, seepage, alternate wetting and drying and so on, the mechanical properties of rock mass are susceptible to be deteriorated, and its strength characteristics are significantly degraded with time.
Introduction Since there are such a variety of inducements as temperature, alternating wet and dry, human activities and other external factors to trigger the damage, the rock slope which contains weak layers and structure planes, its intrinsic physical and mechanical properties of materials are vulnerable to deteriorate, especially its strength characteristics are significantly degraded with time, mesoscopic damage accumulate inside the rock, so its stability becomes a condition that varies with time.
Properties of structures planes generally vary from location to location and may change with time.
Additionally, compared with the bedrock, the properties of the structure planes is more important.
If the rock slope has been in adverse geotechnical environment for a long time, its mechanical properties deteriorate and the failure time of the slope is significantly shortened compared with the same slope in advantage geotechnical environment.
