Slope Instability Hazard Warning System

The research on cataclysmic law of landsliding disaster is the basis of it's research on prewarning system. In the thesis, with long-term forecasting of landsliding disaster as main researching subject, from analyzing the macroscopic failure characteristics and main control factors of slopes sliding, author researched the basis principle, methods and steps of prewarning research of slopes sliding disater.In the thesis, with cataclysmic law, cataclysmic information monitoring and control disaster measures organically combined, author cleared the concept and intension of disastrous prewarning of slope sliding, directed the researching method of disastrous prewarning of slope sliding: with the "White Box" theory as theoretical basis, with disastrous long-term forecasting as main researching object, with disastrous law as researching focal point, with analysis and back analysis to formations provided by the monitoring system with initiative monitoring and passive monitoring combined as main researching method, to establish disastrous prewarning system of slope sliding, provide the basic methods of engineering countermeasure and achieve the informationalized construction of slope engineering.In the research on mechanism of landsliding disaster, with slope stability analysis as researching emphasis, the determinating method of the location of center of critical circular failure surface are discussed. With the energy coefficient as evaluating criterion of landslide, the method and formulae of slope stability analysis of slope which contains weak interlayer are also established. The mechanism of intercalated clay layer water film type landslide is different from other general landslide, from analyzing the macroscopic failure characteristics of intercalated clay layer water film type landslide, author analyzed the main control factors of intercalated clay layer water film type landslide and provided the calculating formulae of the improved limit equilibrium slope stability analysis coefficient.In the research on engineering treat measures, the effective mechanism, influencing factors of anchoring strength and design method of prestressed anchorage cable slope reinforcement technology are discussed and it's working flowchart is also established in the thesis.In the research on monitoring system, the testing criterion of rock mechanic test and the determinating principles of rock mechanic parameters are discussed. Author considered that the monitoring system include initiative monitoring and passive monitoring, and discussed its' intension and using category. The basic discriminating basis for landslide is established in the thesis.
