Research On The Soft Rock Slope Border Deformation And Instability And The Study Of Corresponding Prevention And Curing Techniques

The issue of soft rock was brought up as an international difficult problem in the 1960s'. For years, the problems of theory about the concept and the engineering design of soft rock still have no certain conclusion.The soft rock is a complex rock mechanics medium, which has salience plastic deformation in special environment. The soft rock slope border refers to the structure of the slope is soft rock. The soft rock engineering refers to the rock engineering about plastic deformation of rock. The engineering of the soft rock slope border is one of the engineering of soft rock engineering.In this article, I introduced the research status of the characteristics of soft rock slope border and the research of prevention and curing techniques of the soft rock slope border.Along with the development of the construction, the soft rock problem is more extrude. The soft rock slope border's instability is the most familiar problem in rock slope border engineering. Beginning with the soft rock's physical mechanics character, this article analyzes the effect of original or subsequent geological action to the steadiness of the soft rock character and its slope border, from the aspects of the rock component, physical character, mechanics character, geological structure and weathering, by use of reference of the former study result. And also, it analyzes the related reason of soft rock slope border instability.Aiming at the exterior behavior of the soft rock slope border, according to the research method and development of the domestic and international soft rock analysis, and combining the author's experience in engineering, this article discovers the engineering geological model and the destroy function of the instability of the rock slope border. It analyzed the instability mechanism of the soft rock slope border from the aspects of medium of the soft rock slopeborder's rock character, geological structure action, and rock mechanism.By researching the SRSB instability prevention and curing techniques, the article brings the new method of prevention and curing of the slope border, and points out the corresponding prevention and curing methods to different kinds of soft rock slope border medium status and different kink of instability. Combining the request of environment, it points out the application of prevention and curing method should consider the importance and active aspect of environment protection.At last, combining the soft rock slope border engineering's example, it validates the active aspect of soft rock theory in the application of soft rock instability analyzing, and the active aspect of prevention and curing engineering. It also validates the feasibility and reliability of the corresponding composes of prevention and curing engineering.The research of soft rock slope border instability and its prevention and curing techniques are an important subject. It has wide application future. It would make great contribute to engineering if we discover the subject actively.
