Study On The Anti-slide Structure In Slope Engineering Application

In recent years, with the rapid development of construction, the general sliding piles, prestressed cable sliding piles and other submerged structure in the anti-slide slope engineering to be widely applied, and have achieved good results. However, due to the slope of rock and soil uncertainties, as well as geotechnical and sliding the complexity of the structure interaction, in addition to the general anti-slide pile, the other sliding structure of the design theory and construction methods and technology are still not perfect enough. In order to ensure the safety and slope stability, design is often too conservative, resulting in large bulky structure, serious waste materials; Even so, because of the shortcomings of the theory is still likely to cause structural failure and slope instability. Therefore, how to integrate the actual slope engineering, sliding further deepen structural design theory, practical construction methods and technology, is currently the engineering sector to be the key to solving technical problems. In this paper, the integrated use of engineering investigations, theoretical analysis, geological mechanical means, such as testing the model on the sliding slope engineering structure in the application of some of the key technical issues for a more in-depth study. Major activities include the following:1.A large number of projects based on the actual outcome of the investigation and analysis of domestic and international research to identify the existence of the current anti-slide structure calculation of the design flaws and major projects key technical issues: the role of the structure of the slope pressure, the determination of reasonable pile spacing and the anchoring of prestressed cable length calculation.2.By theoretical analysis, the ordinary anti-slide piles, prestressed cable sliding pile embedded anti-slide pile and the design theory of a more in-depth analysis and research, the corresponding calculation of internal forces. Combined with Northwest Sichuan mine-16 wells, 318 material yard slope engineering, and other examples of the theory and the calculation method was verified analysis, while sliding on the structure of the three projects a comparative analysis of adaptability.3.Combining materials Corporation 318 material yard major indoor geomechanical model test, simulation analysis of the slope in the natural state of the slope failure mechanism and sliding imposed after Supporting measures the stability of retaining structures of reinforcing effect. The excavation was in the process of unloading the slope slope deformation law, tested the anti-slide structure on the slope reinforcement effect. At the same time further validates the reliability of the design theory.4. In the theoretical analysis, model test on the basis of research results, the combination of anti-slide structure in slope engineering application of the actual situation, the structure of confrontation sliding technology, methods and quality control problems were analyzed.
