Strong Sniper Energy Propagation Law And Reinforcement Range

As an Optimum Method of ground treatment,dynamic compaction has been widely applied in foundation reinforcement due to its superiority.Up to now,theoretical research far lags behind practical research as a result of soil complexity.So,dynamic compaction theory guidance for engineering practice has to be perfected by various means is a rather difficult job.We can find that dynamic compaction energy is an important factor to affect the consolidation effect by the previous researchers study on the consolidation mechanism and engineering application on the spot.While at present no detailed study of transmit pattern of dynamic compaction energy is available,through studies on dynamic compaction energy to getting transmit pattern and reinforcement scope and trials to ensure Construction quality and design parameters,it can be stated not only of important theory value,but also of positive reality meaning.It is essential to do separately investigation on a variety of soil due to its great diversity;and the investigation on dynamic compaction energy of red sandstone is of profound significance as it widely distributed over central and Southern areas.Energy allocation and reinforcement scope has been thorough analyzed and researched,based on a lot of domestic and international analysis on dynamic compaction ground treatment and engineering application,has carried on work of relationship between energy and soil nature change in the impact-process of red sandstone by indoor equipment adjustment and model test.The research content as follows:(1)To get energy consumption rules in different layers of temping energy via data analysis;Excel chart established;studies of density,angle of internal friction and cohesion.To get ampingenergyin different soil layer of dissemination rule.(2)To get energy allocation rules by reinforcement scope study.(3)To get reinforcement scope of red sandstone by model test;Distance of tamping points in national standardized document to be further supplemented;To get calculation formula of reinforcement scope by MATLAB software and to find it good practicability by engineering cases checkout.
