Research Progress of Physical Model Test on Slope Reinforcement with Slide-resistant Piles
In order to analyze the research status of slope reinforcement with slide-resistant piles and clarify the mechanism and effect of slope reinforcement with slide-resistant piles,the literature on the physical model test of slope reinforcement with slide-resistant piles in China and foreign countries are reviewed.Firstly,the model test process of slope reinforcement with slide-resistant piles under static,vibration and centrifugal forces are described,and the working mechanism and stress of different types of slide-resistant piles in different rock and soil slopes are analyzed.Secondly,the advantages and disadvantages of the three model tests are compared and analyzed.Finally,the working mechanism and advantages of the combined system of anchor cable slide-resistant piles in slope reinforcement are discussed.The results show that the slope reinforcement with slide-resistant piles have high stability and satisfied effect,and the anchor cable slide-resistant piles combination system can reduce the piles bending moment.The three types of model tests have obvious shortcomings.It is necessary to strengthen the selection of similar materials in the model test,the optimization of loading path,and the accuracy of monitoring instruments,so as to ensure that the actual process of slope deformation and failure can be more accurately restored and more meaningful experimental conclusions and rules can be obtained.
